JUNOSe 11.0.0 Release Notes > Release 11.0.0 > Early Field Trial Features

Early Field Trial Features

The features described in this section are present in the code but have not yet been fully qualified by Juniper Networks. These features are available only for field test purposes in this release. If you use any of these features before they have been fully qualified, it is your responsibility to ensure that the feature operates correctly in your targeted configuration.

ANCP

• Support for Learning the Partition ID from an Access Node

ANCP running on a network access server (NAS) can now learn the partition ID from an access node and use this partition ID to communicate with the access node. In lower-numbered releases, ANCP running on a NAS did not keep track of the partition ID of an access node, and always communicated with partition ID 0. This learning option in the virtual router enables the NAS to learn the partition ID from all the access nodes. The learned partition ID can be used to send messages to establish adjacency.

To learn the partition ID, the NAS has to wait until it receives the first GSMP_SYN message from an access node.

The following command has been added to enable the learning option in the global mode: wait-for-gsmp-syn

The following command has been added to disable the learning option in the virtual router: no wait-for-gsmp-syn.

The following command has been added to change the timer value: gsmp-syn-timeout "value"

The following command has been added to change the timer to the default value of 60 seconds: no gsmp-syn-timeout

In addition, the output of these two commands has been modified:

show configuration

show l2c

DHCP

• Support for DHCP External Server, DHCP Local Server, DHCP Relay, and DHCP Relay Proxy on POS Access Interfaces

The following packet over SONET (POS) module combinations on E Series routers now support configuration of the DHCP external server, DHCP local server, DHCP relay, and DHCP relay proxy applications, alone or in combination, when the POS module is the access interface:

• POS module combinations on the E120 router and the E320 router:

• ES2 4G LM with ES2-S1 OC12-2 STM4 POS IOA
• ES2 4G LM with ES2-S1 OC48 STM16 POS IOA

• POS module combinations on ERX14xx models, ERX7xx models, and the ERX310 router:

• OCx/STMx POS line module with OC3-4 I/O module
• OCx/STMx POS line modules with OC12/STM4 I/O module
• OC48 line module with OC48 FRAME APS I/O module

In the current release, this feature is available for early field test purposes only.

You can configure DHCP external server, DHCP local server, DHCP relay, and DHCP relay proxy on these POS modules in either a virtual router (VR) or a VPN routing and forwarding instance (VRF).

As part of this feature, the pos keyword has been added to the existing ip dhcp-local limit command. To specify the maximum number of IP addresses that the DHCP local server application can supply to all POS access interfaces or to a specific POS access interface, in the range 0-96000, use the ip dhcp-local limit command with the new pos keyword. For example:

! Set the IP address limit for all POS access interfaces to 1000

host1(config)#ip dhcp-local limit pos 1000

! Set the IP address limit for the specified POS access interface to 2000

host1(config)#ip dhcp-local limit interface pos 5/0/0 2000

! Restore the IP address limit for all POS access interfaces to the default value,
! 48000

host1(config)#no ip dhcp-local limit pos

To display the maximum number of IP address leases available for POS access interfaces, use the existing show ip dhcp-local limits command. For example:

host1#show ip dhcp-local limits

*****************************************

     DHCP Local Server Address Limits

ATM Limit      - 48000

VLAN Limit     - 48000

POS Limit      - 1000

Ethernet Limit - 48000

IPv6

• Support for Configuring IPv6 HTTP Redirect URL from Profile Configuration Mode

You can now provide initial provisioning and service selection for the subscriber, by using the IPv6 HTTP redirect URL feature. You use the ipv6 http redirectUrl command from the Profile Configuration mode to specify the URL to which a subscriber's initial Web browser session is redirected, as shown in this example:

host1(config)# profile guidEnt6

host1(config-profile) # ipv6 http redirectUrl http://ispite.redirect.com

The following commands have been enhanced to support this feature:

ipv6 http redirectUrl

show profile

In the current release, this feature is available for early field test purposes only.

System Maximums

• Increased Number of Service Sessions and Subscriber Sessions for E120 and E320 Routers

Beginning with JUNOSe Release 11.0.0, the maximum number of service sessions and subscriber sessions that are supported per chassis for the Service Manager application on E120 and E320 routers are as follows:

Number of Service and Subscriber Sessions per Chassis for Service Manager	E120 Limits	E320 Limits
Service sessions (active)	196,608	262,144
Active subscriber sessions	64,000	96,000

In the current release, this feature is available for early field test purposes only.
