Patch 86251-08 For Rapier Series Switches

47

PCR: 02525

Module: TELNET, PING, IPV6, Network affecting: No

 

TCP

The ADD IPV6 HOST command was not accepting the INTERFACE parameter when adding a host with a link-local address. This issue has been resolved.

PCR: 02527

Module: TCP

Network affecting: No

TCP did not send a TCP Reset message under some circumstances, for example when the Telnet server was disabled. This issue has been resolved.

PCR: 02552

Module: SWI

Network affecting: No

If ingress filtering was supported within trunk groups, ports with ingress filtering enabled were erroneously added to the trunk group. This issue has been resolved.

PCR: 02574 Module: DVMRP

Network affecting: No

Some change actions, and the resending of prune messages were not operating correctly. This issue has been resolved.

PCR: 02581

Module: TM

Network affecting: No

The test facility was not testing switch ports. This issue has been resolved.

ICMP Router Discovery Advertisements

Support for Router This release supports all of RFC 1256, ICMP Router Discovery Messages, 1991 as Discovery it applies to routers. If this feature is configured, the router sends router

advertisements periodically and in response to router solicitations. It does not support the Host Specification section of this RFC.

Benefits Before an IP host can send an IP packet, it has to know the IP address of a neighbouring router that can forward it to its destination. ICMP Router Discovery messages allow routers to automatically advertise themselves to hosts. Other methods either require someone to manually keep these addresses up to date, or require DHCP to send the router address, or require the hosts to be able to eavesdrop on whatever routing protocol messages are being used on the LAN.

Router Discovery See Table 9 on page 48 for a summary of the processes that occur when Router Process Discovery advertisements are enabled for interfaces on the router.
