
When changing the IP address of a VLAN, the previous VLAN IP address would still be advertised to
adjacent devices in the topology tables. This resulted in the "show sys topology" command from the
adjacent boxes still displaying the previous IP address of the neighbour until a cold boot of the neighbour
was performed. This issue is resolved (wi00507312)
DHCP

DHCP Replies are flooded by Relay Agent instead of sending unicast DHCP reply packet. This issue is
resolved (wi00564847).
IP Multicast

A PIM message received on a specific port was discarded if the egress towards the source is on the same
port but different VLAN. This issue is resolved. (wi00564777)

In multicast over SMLT environments, aggregation switches could never age out certain S,G entries even
after the source stopped sending multicast traffic. These stale entries would eventually prevent new entries
from being created and could also result in high cpu utilization. This issue is resolved (wi00697430)
MLT / SMLT

An infrequent scenario has been identified which could result in a CPU reset in the SMLT module during
upgrades to 5.1.2.0. This issue is now resolved. (wi00564781).

The VLAN MAC addresses of an IST peer switch should be learned only via IST links in a normal
operating environment. It has been noted in some transient network scenarios that flooded control plane
packets may be reflected and result in these addresses being learnt temporarily on SMLT links. SMLT
behaviour has now been enhanced to ensure that the IST peer switch VLAN MAC addresses are never
learnt on SMLT links. (wi00733200).

In full mesh SMLT with both LACP and VLACP configured, a higher than expected number of VLACP
packets may be forwarded to the CPU. This issue is resolved (wi00564193).

In ERS 8600 with static-mcast mac configured in a SMLT setup, when the links are disabled/enabled, the
error message "rarIsPortInMgid(4095): Invalid Mgid" was seen. This issue is resolved (wi00564321).

When both aggregation switches in an IST pair are rebooted with SMLT ports disabled in the saved
configuration file, the SMLT state will remain "normal" on one of the switches when the SMLT ports are
subsequently restored. This issue is resolved (wi00564214).

In an LACP SMLT, the SMLT status would incorrectly remain in SMLT state if the established LACP
aggregation times out on the link without a link failure. This issue is resolved (wi00828218)
BGP/VRF

Disable/enable of route-policy configured within a VRF results in a crash because of NULL pointer
dereference. This issue is resolved (wi00564289).

On disabling/re-enabling BGP or doing BGP restart on the VRF, routes updates were not being processed
properly in configurations where VRF 1 was not configured. This issue is resolved (wi00564348).
