Avaya has released software 6.2.3 for the Ethernet Routing Switch 5500/5600 series switches.

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

  • SLPP Guard
    The Switch Clustering implementations on the VSP9000, ERS8800/8600, and ERS5000 provide a Simple Loop Prevention Protocol (SLPP) packet, which operates to help prevent loops from occurring when Switch Clustering is used.
    Simple Loop Prevention Protocol (SLPP) Guard can be used to provide additional loop protection to protect wiring closets from incorrect or faulty connections. When SLPP Guard is enabled, this loop prevention mechanism extends into and across multiple wiring closets. If an edge switch configured for SLPP Guard receives an SLPP packet on a port, the feature can immediately disable the port administratively, and generate appropriate log messages and SNMP traps.

The following issues were resolved in this release;

  • Stack upgrade failure from 6.1.4.011s to 6.2.1.003s with a large config file (wi00882592)
  • Loss of IST VLAN on three unit stack after a base unit failure (wi00885609)
  • Some links get disabled after upgrade from 5.1.x to 6.x (wi00731564)
  • IST Peers FDB table were out of sync (wi00892974)
  • “show spanning-tree rstp port role” command displayed ‘Oper Status’ incorrectly as “disabled” after reboot (wi00899325)
  • After upgrading from 5.1.4 to 6.2.1 EDM routing/IGMP/SNOOPING table expanded indefinitely causing high CPU utilization (wi00886347)
  • Using show running-configuration with 744 VLANs configured, spiked the CPU utilization to 100% for about 12-15 minutes (wi00907462)

Cheers!

SIP Software Release 4.1 Service Pack for IP Deskphones

Avaya has released SIP software release 4.1 Service Pack (4.01.15) for their 1100 and 1200 series IP deskphones. I’ll refer you to the release notes for the 4.1 Service Pack software release for the all the details. Let me also reference the 4.1 (4.01.13) software release notes since I never announced it here.

This release adds support for the following two new features;

‘More’ Feature Key (IP Office)

SIP Software Release 4.1 for 11xx/12xx IP Deskphones introduced a mechanism for IP Office to configure extra features using the soft keys on the deskphone. Soft keys are the 4 buttons located below the display screen on the phone. Soft key button labels are displayed on the phone display right above the physical buttons, with each label corresponds to the physical button. SIP Software Release 4.1 Service Pack for 11xx/12xx IP Deskphones extends this feature by the addition of a ‘More’ key as the right-most button, indicating more selections are available.

Configurable LLDP Timeout

SIP Software Release 4.1 for 11xx/12xx IP Deskphones provides a mechanism to customize the time to wait for LLDP data from the network.

On reset/power-up, the Deskphone will try to obtain LLDP data (i.e. the VLAN ID) only once at startup. If no response is received from the network switch the deskphone will continue to boot. After that the phone will not retry to get LLDP data until the next reboot. In some cases, the network switch may take too much time to start up. In this case, if the switch applies power to its ports (POE) before the switch is ready to accept network packets from devices (the deskphone) connected to the switch, the LLDP negotiation may timeout before the switch is ready to respond.

Prior to SIP Software Release 4.1 Service Pack, following a reboot (and the ENABLE_LLDP flag is set), the deskphone would wait for LLDP data from switch for up to 30 seconds. If no data was received, the deskphone starts up using the previous data stored in EEPROM.

With SIP Software Release 4.1 Service Pack, a new provisioning parameter has been added to the device configuration file to specify the time to wait for LLDP data from the network switch:

LLDP_WAITING_TIME

Minimum value is 30 seconds

Maximum value is 300 seconds (5 minutes).

I haven’t personally seen the issue that Avaya is attempting to resolve regarding the LLDP timer when connecting the 1100 or 1200 series IP phones to the Avaya Ethernet Routing Switch 5520. I have observed that the switch appears to delay enabling PoE on the ports until it’s far enough along through the boot-up process.

Cheers!
