Ethernet Routing Switch 5000 Software Release v6.2.2

Avaya has released software 6.2.2 for the Ethernet Routing Switch 5500/5600 series switches.

Here are some of the highlights from skimming the release notes;

  • VLACP Unidirectional Fault Detection with support for the DOWN and HOLD subtypes (previously implemented in the 6.1.6 software stream)
  • additional 802.1AB (LLDP) TLVs for Avaya IP phones

The following issues were resolved in this release;

  • Inconsistency between CLI MAC_Security Addr & MAC_Addr_Table (wi00895275)
  • MAC- security MAC-Address table would not clear when disabling port or turning off Mac-Security (wi00895279)
  • After Upgrading from 6.1.1 to 6.2.1, QoS configurations were lost (wi00838747)
  • IST stack Ping recovery takes up to 2 minutes when moving PC (wi00822726)
  • Unicast acknowledge (option 85) changed to multicast acknowledge by DHCP-relay agent (wi00835596)
  • Autonegotiation could not be disabled (wi00824799)
  • EAPOL table entries showed MACs that were aged out (wi00831481)
  • In a stack configuration and after adding ports (from a newly added switch) to an existing VLAN, the stack became unstable (wi00731609)
  • SMLT/FDB tables were not completely synchronized when one of the IST peers was reset (wi00774925)
  • SLPP packets were sent with priority 0 (wi00555285)
  • Not able to set PID of Vlan protocol_userdef to 24577 to 24585 (wi00848161) This fix allows the creation of protocol VLANs using decOtherEther2
  • protocol PIDs or of using the PIDs for decOtherEther2 protocol VLANs, but not both. The protocol PIDs are 24576 to 24578, 24581 to 24585, 32824.
  • Incorrect ghost SMLT was created when IST/SMLT stats were displayed (wi00601469)
  • After upgrading from 5.0.5 to 6.2.0, ARPs were not properly generated (wi00851317) This issue was a byproduct of the use of IPFIX on a single port. A fix was implemented for the 5600 HW but, due to HW differences, cannot be implemented for the 5500, a workaround is to use more than one port when using IPFIX. The issue only appeared for the port using IPFIX.
  • IGMP static member (mrouter port) not forwarding multicast after port down/up (wi00895225)
  • Switch does not learn MAC of format xx:59:xx:xx:xx:xx (wi00870510)
  • Units reset when PIM is enabled (wi00848276)
  • Cannot give an IP address to the switch with the last octet as “0″ (wi00872983)
  • IST peer 5632 HD encountered memory leak one hour after upgrade to 6.2.1 (wi00859217)
  • QoS BPDU Blocker settings were not saved on unit 2 after it was rebooted (wi00872260)
  • 5600 ports become unresponsive under certain conditions with no packets transmitted out with “drop on no resources” counter incrementing (wi00854625)

I’m curious to see what performance gains we can expect to see from Enterprise Device Manager (EDM) from this software release. I had heard that they were re-writing it and some of that was supposed to be in software release 5.5 for the Ethernet Routing Switch 4500 series, perhaps some of those changes made it into this software release for the Ethernet Routing Switch 5000 series.

Cheers!

Ethernet Routing Switch 8600 Software Release v5.1.6.0

Avaya Ethernet Routing Switch 8600Avaya has released software v5.1.6.0 for the Ethernet Routing Switch 8600. This release has no new features but instead addresses a number of software bugs. Please refer to the release notes for all the details. There is one bug in particular that I’ve personally seen;

  • Broadcast and multicast traffic that should be flooded within a VLAN is no longer forwarded out the same MLT as it arrived if the ingress port is in the port range 41-48 on an 8648GTR or 8648GTRS card. (wi00867614)

I stumbled across this problem while reviewing the port utilization (MRTG) for a number of switch ports. The ifInOctets and IfOutOctets for the ports didn’t look right so after running a packet capture from the standby CPU/SF and reviewing the trace we could see Multicast frames that were being sourced from the closet being sent back out to the closet.

I’m still working through a high CPU utilization issue with Avaya on an ERS 8600 IST/SMLT cluster running 5.1.5.1 software although I’ll probably try to load 5.1.6.0 in our testlab and see how it runs. I’d love to hear comments back from anyone running 5.1.6.0 software.

Cheers!

Ethernet Routing Swtich 4500Avaya has released software 5.5 for the Ethernet Routing Switch 4500 series switch.

  • 802.1AB customization
  • 802.1AB integration
  • 802.1X non-EAP Accounting
  • 802.1X non-EAP re-authentication
  • 802.1AB new default parameters
  • AUR enhancement
  • DHCP Snooping External Save
  • EAP Fail Open with multi-VLAN
  • Layer 3 Virtual Router Redundancy Protocol
  • RADIUS EAP or non-EAP requests from different servers
  • SLPP Guard
  • SNMP Trap enhancements
  • STP BPDU filtering ignore-self
  • Unified Authentication
  • VLACP enhancements
  • Enterprise Device Manager enhancements
  • Web server client browser requests

The known issues and resolved issues are mysteriously blank although there is a note there that indicates those sections will be updated on May 20, 2011.

Please refer to the release notes for all the specific details and tidbits.

It appears that Avaya is trying to address the performance issues with EDM that many of us have documented;

Enterprise Device Manager enhancements

In Release 5.5 Enterprise Device Manager (EDM) is enhanced with improved data retrieval and request handling for significantly faster GUI response. In the navigation tree the IP Routing folder is renamed IP and the paths in related procedures have been updated. The Switch Summary tab contents have been enhanced to include basic switch information and stack information. A toolbar has been added above the EDM navigation tree. The 5 buttons in the toolbar add the following functions:

  • Switch Summary — you can use the Switch Summary toolbar button to open or reopen the switch summary tab.
  • Refresh Status — in addition to the existing refresh methods you can use the Refresh Status toolbar button to refresh the device status.
  • Edit Selected — in addition to the existing edit methods, and depending on which object you select on the Device Physical View, you can use this toolbar button to open Edit > Chassis, Edit > Unit, or Edit > Ports tabs. If you do not select an object from the Device Physical View and you click the Edit Select toolbar button, the Edit > Chassis tab opens.
  • Graph Selected — depending on which object you select on the Device Physical View, you can use this toolbar button to open Graph > Chassis or Graph > Port tabs. If you do not make a selection on the Device Physical View, or if you select Unit, the Graph > Chassis tab opens.
  • Help Setup Guide — this button connects you to the help setup guide for embedded EDM and it replaces the link that appeared on the top right of work panes.

Cheers!
