Outstanding Issues - Avaya ERS 8600 Manual

VLACP

If a mismatching VLACP configuration exists on two ends of a connection associated with a SLT, the SLT will
no longer show as SMLT up improperly after a reboot. (Q02119095)
VRRP

Enabling and then disabling the IST protocol will no longer lead to improper values displayed in the VRRP
records. (Q02106080-01)
BFD

On a ERS8600 running both BGP and BFD, when one tries to enable BGP first and then BFD on the BGP
neighbour, the BFD related config can now be set properly. (Q02141063)
Outstanding Issues
Please refer to the Outstanding Issues Section of the Release Notes for Ethernet Routing Switch 8600 Software Release
5.1.0.0. Additionally, the following issues have also been classified outstanding issues.

For a tagged R/RS module port, the ERS 8600 will improperly not honor the QoS marking of incoming packets
that need to also be copied to the CPU, i.e. network control packets. These packets will instead be sent to the
default queue for the CPU. This situation only has the potential to create operational issues for situations
where the CPU utilization is already abnormally high, which is a situation that always needs looking at to start
with. (Q02131463)

In HA-CPU environments, when the Master CPU card is pulled out and re-inserted, some line cards may lose
communication with the master CPU and may have to be re-inserted. Physical removal of the master SF/CPU
is not a recommended or supported action. A switchover to secondary CPU is recommended to be performed
first. (Q02128408)

System instability has been reported infrequently during handling of OSPF updates. Analysis of the system
data related to this issue indicates a strong correlation to the infrequent memory corruption already addressed
in 5.1.2.0 under Q02093533 and Q02106560. A similar intermittent instability has been reported within SNMP
which is also currently believed to be linked to the memory corruption addressed in 5.1.2.0. (Q02125441,
Q02118856)

Statistics related to ACE filters for R/RS modules may not increment/decrement properly. When running the
"show filter acl statistics port" command, the fields for "the number of packets" and "bytes" may show up as all
zeros. This is seen in all 5.1.x, not just 5.1.3.0. (Q02128334)

In ERS 8600, certain routes may get deleted in the IP routing table on deleting/adding both a route policy and
triggering a soft restart of an associated BGP peer. If encountered, this can be recovered by restarting the
BGP session to the peer, or disable/enable BGP globally. (Q01976477)

A very unlikely timing scenario can result in the system monitor falsely detecting tTrapd task in loop.

(

In highly scaled configurations with large number (hundreds) of SLTs and VLANs, one may encounter few
seconds of traffic loss upon recovery of an aggregation switch after a reboot.(Q02138421)

Jamie – do we really need this to be documented? (

With static multicast MAC configured and no port configured on the static multicast mac, one may notice "HW
ERROR rarIsPortInMgid: Invalid Group (4095)!" line in the log file (Q02144094)
