Early Field Trial Features
Change in existing behavior: Existing feature extended as described here. You can
now perform a conventional upgrade from releases numbered lower than Release
11.3.0 to Release 11.3.0, if the router chassis contains ES2 10G LMs or REV-02 versions
of the ES2 10G LM. In lower-numbered releases, you could only download the image
from serial Programmable Read-Only Memory (PROM), which was a factory image.
You still cannot perform a unified ISSU operation from releases numbered lower
than Release 11.3.0 to Release 11.3.0, if the router chassis contains ES2 10G LMs.
Support for IP Reassembly for Dedicated Tunnel Server Configured on an ES2 10G
ADV LM
An ES2 10G ADV LM and Service IOA combination provides a dedicated tunnel server.
When packets larger than the MTU of the tunnel interface are sent through the
tunnel, they may be fragmented. However, tunnel processing requires each packet to
be a complete packet, the way it was before it got fragmented.
To support this, fragmented packets are now reassembled on an ES2 10G ADV LM
before they are sent for tunnel processing.
Change in existing behavior: Existing feature extended as described here. In
lower-numbered releases, the IP reassembly for dedicated tunnel-server was
supported only when configured on the ES2 4G LM.
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.
