Removing Overriding Profile Assignments from a VLAN Range or VLAN Subrange

When you issue the no vlan bulk-config command to remove an entire VLAN range (and all VLAN subranges within that VLAN range), the router also removes any overriding profile assignments configured for VLAN IDs within those VLAN subranges. For example, the following command removes the bulk-configured VLAN range named myBulkConfig and any overriding profile assignments for VLAN IDs within the VLAN subranges belonging to myBulkConfig.

When you issue the no vlan bulk-config command to remove a particular VLAN subrange in a bulk-configured VLAN range, the router also removes any overriding profile assignments for VLAN IDs within that VLAN subrange. However, overriding profile assignments for VLAN IDs within other VLAN subranges in the VLAN range remain intact. For example, the following command removes one VLAN subrange (S-VLAN IDs 50–150 and VLAN IDs 150–250) and only those overriding profile assignments associated with this subrange.

auto-configure vlan

• Use to configure the static VLAN major interface to support autodetection of an VLAN dynamic interface type.
• You must issue this command to enable creation of a dynamic VLAN subinterface.
• By default, all valid VLAN IDs and S-VLAN IDs are accepted.
• Example

  host1(config-if)#auto-configure vlan

• Use the no version to terminate autodetection of the VLAN dynamic interface type.
• See auto-configure vlan.

encapsulation vlan

• Use to configure VLAN as the encapsulation method for the interface.
• Example

  host1(config-if)#encapsulation vlan

• Use the no version to disable VLAN on an interface.
• See encapsulation vlan.

interface fastEthernet

• Use to select a Fast Ethernet interface.
• For information about specifying a Fast Ethernet interface, see interface fastEthernet.
• Example

  host1(config)#interface fastEthernet 4/1

• Use the no version to remove IP from an interface or a subinterface.
• See interface fastEthernet.

interface gigabitEthernet

interface tenGigabitEthernet

• Use to select a Gigabit Ethernet interface or a 10-Gigabit Ethernet interface.
• To specify a Gigabit Ethernet interface for ERX-7xx models, ERX-14xx models, and ERX-310 routers, use the slot/port[.subinterface ] format.
• To specify a Gigabit Ethernet interface or 10-Gigabit Ethernet interface for E120 and E320 routers, use the slot/adapter/port[.subinterface ] format.
• For more information, see chapter Configuring Ethernet Interfaces in JUNOSe Physical Layer Configuration Guide.
• Examples

  host1(config)#interface gigabitEthernet 1/0

  host1(config)#interface gigabitEthernet 4/0/1

  host1(config)#interface tenGigabitEthernet 4/0/1

• Use the no version to remove IP from an interface. You must issue the no version from the highest level down; you cannot remove an interface or subinterface if the one above it still exists.
• See interface gigabitEthernet.
• See interface tenGigabitEthernet.

profile

• Use to create a base profile to configure attributes for a dynamic VLAN subinterface.
• Specify a profile name of up to 80 alphanumeric characters.
• Example

  host1(config)#profile vlanBaseProfile

• Use the no version to delete the specified profile.
• See profile/

profile vlan bulk-config

• Use to assign the base profile configured for a dynamic VLAN subinterface to the single-tagged VLAN IDs or double-tagged S-VLAN IDs configured on a static VLAN major interface.
• You must specify both of the following:
  • Name assigned to the VLAN range on a VLAN subinterface, as specified in vlan bulk-config
  • Name assigned to the base profile for a dynamic VLAN subinterface
• Example

  host1(config-if)#profile vlan bulk-config myBulkConfig vlanBaseProfile

• Use the no version to remove the base profile assignment.
• See profile vlan bulk-config.

profile vlan override bulk-config

• Use to assign an overriding profile to a single VLAN ID or double-tagged S-VLAN ID.
• Using an overriding profile enables you to assign a special profile for the subscribers associated with a specific DSLAM.
• You can also use an overriding profile to troubleshoot the specified VLAN or S-VLAN by overriding the currently assigned base profile with one that has debugging attributes enabled.
• Use the any keyword to specify a VLAN ID as a wildcard. When you specify the any keyword with an S-VLAN ID of a DSLAM, all subscribers associated with the DSLAM will be created with the same profile.
• Example 1—Assigns an overriding profile (test1OverridingProfile) to the dynamic VLAN subinterface with VLAN ID 202

  host1(config-if)#profile vlan override bulk-config vlan 202 test1OverridingProfile

• Example 2—Assigns an overriding profile (test1DebugProfile) to the S-VLAN subinterface with S-VLAN ID 100 within the VLAN subinterface with V-LAN ID 202

  host1(config-if)#profile vlan override bulk-config svlan 100 202 test1OverridingProfile

• Example 3—Removes the overriding profile assignment from the VLAN subinterface with VLAN ID 202, and restores the original base profile assignment

  host1(config-if)#no profile vlan override bulk-config vlan 202 test1OverridingProfile

• Use the no version to remove the overriding profile assignment for the VLAN ID or S-VLAN ID and restore the original base profile assignment.
• See profile vlan override bulk-config.

shutdown

• Use to disable an interface.
• When you disable a dynamic VLAN subinterface, the shutdown command deletes the VLAN dynamic subinterface column and removes the dynamic VLAN subinterface.
• Example

  host1(config-subif)#shutdown

• Because the shutdown command removes the dynamic VLAN subinterface from the router, issuing a subsequent no version of this command has no effect; that is, it does not restart the disabled subinterface.
• See shutdown.

svlan ethertype

• Use to specify the available Ethertypes that a packet must use to create a dynamic VLAN subinterface.
• Choose one of the following Ethertype values:
  • 8100—Specifies Ethertype value 0x8100, as defined in IEEE Standard 802.1q
  • 88a8—Specifies Ethertype value 0x88a8, as defined in draft IEEE Standard 802.1ad
  • 9100—Specifies Ethertype value 0x9100
  • autoconfig—Specifies that the packet can use any Ethertype to create a dynamic VLAN subinterface
• Examples

  host1(config-profile)#svlan ethertype 8100

  host1(config-profile)#svlan ethertype autoconfig

• Use the no version to restore the default value, autoconfig.
• See svlan ethertype.

vlan advisory-rx-speed

• Use to set an advisory receive speed for VLAN subinterfaces that are created with the profile you are configuring. This setting has no effect on data forwarding. You can use it to indicate the speed of the client interface. When traffic is tunneled with L2TP, the advisory receive speed is sent from the LAC to the LNS. See LAC Configuration Prerequisites for additional information about the advisory receive speed.
• The range is 0–2147483647 kbps; 0 indicates no advisory speed setting.
• Example

  host1(config-profile)#vlan advisory-rx-speed 2000

• Use the no version to restore the default behavior—the Rx speed is not sent to the LNS.
• See vlan advisory-rx-speed

vlan advisory-tx-speed

• Use to set an advisory connect speed for VLAN subinterfaces that are created with the profile that you are configuring. This setting has no effect on data forwarding. You can use it to indicate the speed of the client interface. When traffic is tunneled with L2TP, the advisory receive speed is sent from the LAC to the LNS. See LAC Configuration Prerequisites for additional information about the advisory receive speed.
• The range is 0–2147483647 kbps; 0 indicates no advisory speed setting.
• Example

  host1(config-profile)#vlan advisory-tx-speed 2000

• Use the no version to restore the default behavior—the Tx speed is not sent to the LNS.
• See vlan advisory-tx-speed.

vlan auto-configure

• Use to specify the types of dynamic upper-interface encapsulations that are accepted or detected by a dynamic VLAN subinterface.
• Include this command in the base profile for a dynamic VLAN subinterface.
• Use the lockout-time keyword to specify the minimum and maximum lockout time range for the encapsulation type. For more information, see Encapsulation Type Lockout.
• Example

  host1(config-profile)#vlan auto-configure ip

• Use the no version to terminate detection of the specified encapsulation type.
• See vlan auto-configure.

vlan auto-configure agent-circuit-identifier

• Use to create a VLAN subinterface that is based on the agent-circuit-id information in the option 82 field of DHCP messages or in the DSL Forum VSA 26-1 of PPPoE PADR and PADI packets.
• Include this command in the base profile for a dynamic VLAN subinterface.
• Example

  host1(config-profile)#vlan auto-configure agent-circuit-identifier

• Use the no version to disable creation of VLAN subinterfaces based on agent-circuit-identifier information.
• See vlan auto-configure agent-circuit-identifier.

vlan bulk-config

• Use to create a bulk-configured VLAN range on a static VLAN major interface for use by a dynamic VLAN subinterface.

  Note: For information about the maximum number of VLAN bulk configurations supported per chassis, see JUNOSe Release Notes, Appendix A, System Maximums.

• Each VLAN range consists of one or more nonoverlapping VLAN subranges. A VLAN subrange is a group of VLAN IDs or S-VLAN IDs that reside within the VLAN range you specify.
• You can configure multiple VLAN ranges on a VLAN subinterface.
• When you create a bulk-configured VLAN range, you must specify the following:
  • A name of up to 80 alphanumeric characters; this is also referred to as the bulk configuration name
  • The starting and ending VLAN ID or S-VLAN ID values (inclusive) for each VLAN subrange
• Use the any keyword to specify a VLAN ID as a wildcard. When you specify the any keyword with an S-VLAN ID of a DSLAM, all subscribers associated with the DSLAM will be created with the same profile.
• Use the agent-circuit-identifier keyword to configure a VLAN range that is based on the agent-circuit-id information in the option 82 field of DHCP messages or in the DSL Forum VSA 26-1 of PPPoE PADR and PADI packets. When you specify the agent-circuit-identifier keyword with an S-VLAN ID of a DSLAM, all subscribers associated with the DSLAM are created with the same profile.
• You can create a placeholder VLAN range by issuing the vlan bulk-config command without specifying any subranges. You can assign a profile to this placeholder and add subranges to it later.
• You can add and remove individual VLAN subranges.
• You cannot remove a VLAN subrange if any dynamic VLAN subinterfaces currently exist within the subrange. Use the vlan bulk-config shutdown command to remove dynamic VLAN interfaces created within a subrange.
• Removal of a subrange automatically results in the removal of all overriding profile assignments on that subrange.
• You can create a bulk-configured VLAN subrange that includes the VLAN IDs and S-VLAN IDs belonging to an existing VLAN major interface on a static VLAN subinterface.
• Example 1—Configures a VLAN range named myBulkConfig with a single VLAN subrange containing VLAN IDs 100–500

  host1(config-if)#vlan bulk-config myBulkConfig vlan-range 100 500

• Example 2—Configures a VLAN range named myMultiBulkConfig with two VLAN subranges containing S-VLAN IDs 101–600 with VLAN IDs 0–1 (first subrange) and S-VLAN IDs 201–3200 with VLAN IDs 3–5 (second subrange)

  host1(config-if)#vlan bulk-config myMultiBulkConfig svlan-range 101 600 0 1 svlan-range 201 3200 3 5

• Example 3—Configures a VLAN range named myAciBulkConfig containing S-VLAN IDs 200–400. Subscriber information is determined by the packet’s agent-circuit-identifier information.

  host1(config-if)#vlan bulk-config myAciBulkConfig svlan-range 200 400 agent-circuit-identifier

• Use the no version to remove the specified VLAN range from the VLAN interface, to remove the specified subranges from the specified VLAN range, or to remove all subranges from the specified VLAN range. The no version also removes any overriding profile assignments for VLAN major interfaces within the deleted VLAN range or VLAN subrange.
• See vlan bulk-config.

vlan description

• Use to assign a description to VLAN subinterfaces that are created with this profile.
• You can use a maximum of 64 characters for the description or to name the alias.
• Example

  host1(config-profile)#vlan description test1

• Use the no version to remove the VLAN description.
• See vlan description.

vlan policy

• Use to assign a VLAN policy list to an interface.
• Use the input or output keyword to assign the policy list to the ingress or egress of the interface.
• You can enable or disable the recording of routing statistics for bytes and packets affected by the policy.
• If you enable statistics, you can enable or disable baselining of the statistics. The router implements the baseline by reading and storing the statistics at the time the baseline is set and then subtracting this baseline whenever baseline-relative statistics are retrieved.
• You must also enable baselining on the interface with the appropriate baseline command.
• You can use the preserve keyword to save the existing statistics when you attach a policy to an interface that already has a policy attached. This keyword saves the statistics for any classifier-list that is the same for both the new and old policy attachments. Without the preserve keyword, all statistics are deleted when you attach the new policy.

  For example, when you replace a policy attachment that references the original policy-list plOne with a new attachment referencing policy-list plTwo, the existing statistics for the classifier group referencing clOne and the default classifier group are saved.

  Original Policy Attachment	New Policy Attachment	Comment
  ip policy-list plOne	ip policy-list plTwo	–
  ip classifier-list clOne	ip classifier-list clOne	statistics from plOne are saved
  Forward	Forward	–
  ip classifier-list clTwo	ip classifier-list clFour	–
  Forward	Forward	–
  ip classifier-list clThree	ip classifier-list clFive	–
  Forward	Forward	–
  classifier-list *	classifier-list *	statistics from plOne are saved
  Filter	Filter	–

• Example

  host1(config-profile)#vlan policy input VlanPolicy33 statistics enabled preserve

• Use the no version to remove the association between a policy list and an interface or a profile.
• See vlan policy.

vlan profile

• Use to add a nested profile assignment to a base profile for a dynamic VLAN subinterface.
• A nested profile assignment references another profile that configures attributes for a dynamic upper-interface type over the VLAN subinterface.
• Examples

  host1(config-profile)#vlan profile pppoe vlanProfilePppoe

  host1(config-profile)#vlan profile ip vlanProfileIP

• Use the no version to remove the profile assignment for the upper-interface encapsulation type.
• See vlan profile.

vlan service-profile

• Use to specify a service profile name for a dynamic VLAN and to enter Service Profile Configuration mode. Service profiles contain user and password information, and are used in route maps for subscriber management and to authenticate subscribers with RADIUS.
• You can specify a service profile name with up to 80 alphanumeric characters.
• Example

  host1(config)#vlan service-profile vlanClass1Service

  host1(config-service-profile)#

• Use the no version to delete the service profile.
• See vlan service-profile.
