JUNOSe 11.1.0 Release Notes

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.

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

Policy Management

• Support for CAM Classifier Size of Larger Than 144 Bits

You can now configure content-addressable memory (CAM) hardware classifier entries to be greater than 144 bits for IPv6 policies on the ES2 10G LM or the ES2 10G Uplink LM. All different sizes of CAM classification entries like 144, 288, and 576 bits are supported. This feature is limited in this release to early field trial purposes only.
