Known Limitations; Documentation Corrections - Avaya ERS 8600 Manual


In systems 8692 with Supermezz, pulling out and re-inserting line cards may result in instability that may cause
traffic loss. (Q02120668)

Statistics related to ACE filters for R/RS modules may not increment/decrement based on traffic. When
running "show filter acl statistics port" command, the fields "the number of packets" and "bytes" may show up
as all zeros. This is seen in all 5.1.x. (Q02128334)

Incorrect values are displayed under the "ingress rec in-use" column while executing the CLI command "show
ip mroute-hw record-usage". This appears to be introduced in 5.1.x code stream. (Q02120442)

In ERS 8600, certain routes get deleted in the IP routing table on deleting/adding the route policy and triggering
a soft restart of the BGP peer. If encountered, this can be recovered by restarting the BGP session to the
peer, or disable/enable BGP globally. (Q01976477)
Known Limitations
Please refer to the Known Limitations Section of the Release Notes for Ethernet Routing Switch 8600 Software Release
5.1.0.0. Additionally, the following issues have also been classified as operation not to be changed.

ERS8600 might have an I/O module COP (I/O co-processor) crash in an HA configuration, if master/standby
SF/CPU reset/reboot interaction is not properly performed. If resetting or rebooting the master, allow the
standby to take over as new master before any additional resets or reboots are attempted. When resetting or
rebooting the standby, make sure the master recognizes the standby is now off-line (5-10 seconds generally)
before any additional reset or reboot activity on master is performed. (Q02068289)

On upgrading an ERS 8600 from v5.1.2.0 to v7.0.0.0, there can be a corruption seen in the Radius Secret Key.
This is because the new encryption/decryption algorithm meant for Radius Secret Key file (added in v7.0.0.0) is
not supported in 5.1.2.0. (Q02113877)
