# Creating a Subscription to BoD Services

When you create a subscription to a BoD service, you initially set a bandwidth level if available and not previously set. Tasks to create a subscription are:

1. Setting a Bandwidth Level
2. Adding Subscriptions to BoD Services

## Setting a Bandwidth Level

To create a subscription to a bandwidth level:

1. In the navigation pane of Enterprise Manager Portal, click the subscriber for whom you want to provision bandwidth.
2. Click the Bandwidth & VPNs tab.

   | Note: If VPN features are not configured, the tab is named Bandwidth.

   The Bandwidth & VPNs page appears.

   Figure 18: Bandwidth & VPNs Page

3. Using the field description below, select a bandwidth level, and click Apply.

   The bandwidth level becomes available, and the fields for setting BoD services appear on the Bandwidth page.

## Bandwidth Level Fields in Enterprise Manager Portal

Use the field in this topic to define the bandwidth level.

Bandwidth Level

- Bandwidth assigned to an access link (the basic BoD service in the directory). The bandwidth level governs the overall bandwidth available on the link.

- Value—Menu of bandwidth levels in the directory available for this subscriber. See the online help for information about the menu entries.

- Guidelines—A subscriber can be assigned to up to one bandwidth level on an access link.

  In the navigation pane, a subscriber subordinate to the one who has the bandwidth level subscription inherits the subscription. A subordinate subscriber cannot subscribe to another bandwidth level.

  If you select default for the value, all traffic is treated the same.

- Default—Bandwidth level specified as the default by the service provider.

## Adding Subscriptions to BoD Services

To add a subscription to a BoD service:

1. In the navigation pane of Enterprise Manager Portal, click the subscriber to assign to a BoD service.
2. Click the Bandwidth & VPNs tab.
3. If a bandwidth level has not been set, specify a bandwidth level.

   The bandwidth level becomes available, and the fields for setting BoD services appear on the Bandwidth & VPNs page.

   Figure 19: Bandwidth & VPNs Page with a Bandwidth Level Set

4. Click Create Bandwidth Rule.

   The Create Rule dialog box appears.

5. Using field values to configure subscriptions for BoD services.

   See BoD Service Fields in Enterprise Manager Portal

   You can configure any number of subscriptions by assigning different traffic flows, identified by rules under Affected Traffic on the Bandwidth & VPNs page, to different BoD services.

6. Click Create.

   The subscription appears in the Bandwidth & VPNs page.

## BoD Service Fields in Enterprise Manager Portal

Use the fields in this topic to configure subscriptions for BoD services.

Rule Name

- Name of the BoD rule.

- Value—Alphanumeric characters without spaces

- Default—No value

- Example—SalesVideoConference

IP Protocols

- IP protocol associated with traffic affected by this bandwidth rule.

- Value—One of the following:
  - ah—authentication header
  - egp—exterior gateway protocol
  - esp—Encapsulating Security Payload
  - gre—generic routing encapsulation
  - icmp—Internet Control Message Protocol
  - igmp—Internet Group Management Protocol
  - ipip—IP over IP
  - ospf—Open Shortest Path First
  - pim—Protocol Independent Multicast
  - rsvp—Resource Reservation Protocol
  - sctp—Stream Control Transmission Protocol
  - tcp—Transmission Control Protocol
  - udp—User Datagram Protocol
  - <ipProtocolNumber>

- Guidelines—Specify an IP protocol or its corresponding number if you want to enable BoD for a certain type of traffic. If you want to enable BoD for all IP protocols, leave this field empty. If you specify an IP protocol other than TCP or UDP, the port fields will dim, and you will not be able to specify port numbers for this subscription.

- Default—No value

- Example—tcp

ToS Byte

- ToS byte in the header of the IP datagram associated with traffic affected by this bandwidth rule.

- Value
  - DiffServ—DiffServ is used to classify packets by the selected value.
  - Precedence—Value of the drop precedence.
  - Free Format—ToS byte in binary format.

Use an x to indicate a bit to be ignored.

- Guidelines—You can configure the ToS byte only if the configuration level is set to Advanced (see Setting the Configuration Level for Enterprise Manager Portal).

  Specify the ToS byte in this field if you want to enable BoD for a specific type of service. If you want to enable BoD for all types of service, leave this field empty.

- Default—No value

- Example—Free Format 000010xx

Source IP Addresses

- Source IP address(es) (contained in the IP packets) of traffic affected by this bandwidth rule.

- Value—[ not ]<networkAddress>/<networkMask>
  - not—Address, or set of IP addresses as expressed by the netmask, for which the BoD service is not available
  - <networkAddress>—IP address of the network
  - <networkMask>—Netmask expressed as an integer 0–32, which specifies how many of the first bits in the address specify the network

- Guidelines—To specify traffic not from a source IP address or not from a set of IP addresses as expressed by the netmask, precede the IP address with the keyword not. To specify traffic with any source IP address, leave the field empty.

  The order in which you list prefixes, identified by the IP address–netmask pair, is not significant. They are all evaluated to determine whether a match occurs. If prefixes overlap, longest-match rules are used to determine whether a match occurs. For an address to be considered a match, it must match one of the rules in the list.

  For information about how JUNOS routing platforms evaluate prefixes, see the JUNOS Policy Framework Configuration Guide.

- Default—No value

- Example—In this example for a JUNOS routing platform, all IP addresses on the subnet 172.16.0.0/10 are specified, except for those on the subnet 172.16.2.0/16.

172.16.0.0/10, not 172.16.2.0/16

Source Ports

- Source TCP/UDP port(s) (contained in the IP packets) of traffic affected by this bandwidth rule.

- Values
  - Port number
  - Comma-separated list of port numbers and ranges of port numbers (JUNOS routing platforms)
  - Ranges of port numbers separated by two dots (..)

- Guidelines— To specify all ports, leave this field empty. If you specify an IP protocol other than TCP or UDP for this subscription, the port field will dim, and you will not be able to specify port numbers in this field.

- Default—No value

- Example
  - 2
  - 2, 3, 45..55

Destination IP Addresses

- Destination IP addresse(es) (contained in the IP packets) of traffic affected by this bandwidth rule.

- Value—[ not ]<networkAddress>/<networkMask>
  - not—Address, or set of IP addresses as expressed by the netmask, for which the BoD service is not available
  - <networkAddress>—IP address of the network
  - <networkMask>—Netmask expressed as an integer 0–32, which specifies how many of the first bits in the address specify the network

- Guidelines—To specify traffic not to a destination IP address or not to a set of IP addresses as expressed by the netmask, precede the IP address with the keyword not.

  The order in which you list prefixes, identified by the IP address–netmask pair, is not significant. They are all evaluated to determine whether a match occurs. If prefixes overlap, longest-match rules are used to determine whether a match occurs. For an address to be considered a match, it must match one of the rules in the list.

  For information about how JUNOS routing platforms evaluate prefixes, see the JUNOS Policy Framework Configuration Guide.

- Default—No value

- Example—192.0.2.0/24

Destination Ports

- Destination TCP/UDP port(s) (contained in the IP packets) of traffic affected by this bandwidth rule.

- Value
  - Port number
  - Comma-separated list of port numbers and ranges of port numbers (JUNOS routing platforms)
  - Ranges of port numbers separated by two dots (..)

- Guidelines—To specify all ports, leave this field empty. If you specify an IP protocol other than TCP or UDP for this subscription, the port field will dim, and you will not be able to specify port numbers in this field.

- Default—No value

- Example
  - 2
  - 2, 3, 45..55

TCP Flags

- Conditions in the TCP flags in the TCP message header. This field is enabled when the TCP protocol is selected.

- Guidelines—You can enter a value for TCP flags only if you select TCP as the IP protocol.

  You can enter a logical expression that contains the symbols for the six TCP flags: urgent, ack, push, rst, syn, and fin. You can use the following logical operators in the list of flags:

  - &—And. Separates flag settings in the list.
  - !—Not. Flags preceded by ! are cleared; flags not preceded by ! are set.

  You can use the following expression instead of the entire expression:

  - tcp-initial—syn & !ack

  The interface displays text synonyms for expressions if stored data matches the expression.

  This field appears enabled only if the configuration level is set to Advanced. Although the value can be changed when the configuration level is set to Normal, we recommend that the value of this field not be changed if the field appears disabled.

- Default—No value

- Example
  - syn
  - tcp-initial

Fragmentation Flags

- Logical expression using the dont-fragment, more-fragments, and reserved IP fragmentation flags.

- Value—Flags expression

- Guidelines—The expression can also contain the following logical operators:

  - !—Not. Flags preceded by ! are cleared; flags not preceded by ! are set.

- Default—No value

- Example
  - more-fragments
  - ! dont-fragment

Fragment Offset

  - Symbolic name for an ICMP message type
  - Comma-separated list of ICMP types and ranges of ICMP types
  - Ranges of ICMP types separated by two dots (..) within the range 0–255
  - Blank—Any ICMP type

- Guidelines—You can enter a value for this field only if you select the icmp protocol (protocol number 1).

The following list shows the symbolic name and associated numbers for ICMP types. The ICMP types are the same as those on JUNOS routing platforms with the addition of traceroute.

- 0—echo-reply

- Value—Menu of BoD services available for this subscriber. See the online help for information about the menu entries.

- Guidelines—How BoD services define bandwidth allocation depends on whether or not a bandwidth level is set:
  - On a link that has a bandwidth level set, the BoD service defines the transmission service and the forwarding priority of the traffic for the subscription—for example, expedited or best-effort.
  - On a link that does not have bandwidth allocated, the BoD service typically specifies the fixed bandwidth level available to the traffic type for the subscription.

- Default—BoD service with lowest alphanumeric name in the directory
