Early Field Trial Features
DHCP
Release 10.0.3 is a maintenance release.
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.
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
