Patch 86253-07 For Rapier Series Switches

SHOW IGMPSNOOPING ROUTERADDRESS

PCR: 31145

Module: SWI

Level: 3

The port counters were not incremented:

•ifInDiscards

•ifinErrors

•ifOutDiscards

•ifOutErrors

This issue has been resolved.

PCR: 31146

Module: SWI

Level: 3

The following SNMP MIB objects could not be set:

•Dot1dStpPriority

•Dot1dStpBridgeMaxAge

•Dot1dStpBridgeHelloTime

•Dot1dStpBridgeForwardDelay

This issue has been resolved.

PCR: 31147 Module: DHCP

Level: 3

DHCP was incorrectly using the directly connected network interface source IP address as the source IP address of packets it generates. This issue has been resolved. DHCP now uses the local IP address as the source address for the packets it generates when a local IP interface address is set. If a local IP interface address is not set, then it uses the IP address of the interface where packets are sent from as the source address.

PCR: 31148

Module: PIM, PIM6

Level: 2

When the device rebooted with PIM or PIM6 enabled, it sometimes did not send a Hello packet quickly enough. This issue has been resolved.

PCR: 31152 Module: DHCP

Level: 2

When a DHCP client was in the renewing state, and it sent a DHCP Request, the device did not add the ARP entry to the ARP table. Instead, the device generated an ARP Request in order to transmit the DHCP Ack. This caused a broadcast storm in the network when the client kept sending DHCP Requests. This issue occurred because the ciaddr field, not the giaddr field, was checked in the Request packet when the device determined whether to add the ARP entry. This issue has been resolved.

PCR: 31154

Module: STP

Level: 4

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.
