Patch 86261-04 For Rapier and AT-8800 Series Switches SHOW IGMPSNOOPING ROUTERADDRESS 7
Patch 86261-04 for Software Release 2.6.1
C613-10386-00 REV D
The current implementation of RSTP conforms to the IEEE standard
802.1w-2001. However, several minor deviations from the standard are
possible without having a functional impact on the behaviour of RSTP.
These changes are useful for debugging RSTP, and tidy up aspects of RSTP
that sometimes have no purpose. The following three variations have been
implemented:
•The Learning and Forwarding flags are set in BPDUs to indicate the state
of the Port State Transition state machine.
•The Agreement flag is set in BPDUs only when a Root Port is explicitly
agreeing to a proposal from a designated port. Do not set the Agreement
flag in BPDUs transmitted by Designated Ports.
•The Proposal flag is not set in a BPDU sent by a designated port once the
port has reached the forwarding state.
On AT-8800 series switches, when the fan status changed, the device did not
send a SNMP trap and log. When the temperature was above the allowable
threshold, the device sent the wrong SNMP trap. This issue has been
resolved. Also, the temperature thresholds of the AT-8824 and AT-8848 have
been set to different values of 62º C and 67º C respectively.
Static ARP entries sometimes prevented the firewall from working
correctly. This is because when an VLAN interface is added to the firewall,
the CPU takes over the routing from the switch silicon in order to inspect
the packet. Hence all the Layer 3 route entries must be deleted. However,
static ARP Layer 3 entries were not being deleted from the silicon. This issue
has been resolved. When interface is added to the firewall, all hardware
layer 3 routing is now turned off to allow the firewall to inspect packets.
If the number of messages to be stored in the TEMPORARY log output was
changed with the SET LOG OUTPUT MESSAGE command, the SHOW
LOG command output did not return any matching log messages. This
issue has been resolved. Existing messages are now displayed.
A STP topology change incorrectly deleted static ARP entries. This issue has
been resolved.
IP MVR member ports were not timing out. MVR member ports now
timeout in the same way as IP IGMP ports. The timeout values are
configured by IGMP. Also, IGMP interfaces were incorrectly being enabled
and disabled by MVR. This issue has been resolved.
After an AT-8800 series switch was powered down or rebooted, non-auto
negotiating copper GBICs were not handled correctly. This issue has been
resolved.
