Patch 86222-21 For Rapier Switches and AR800 Series Modular Switching Routers

13

PCR: 02039

Module: IPG

Network affecting: No

The SHOW IP ROUTE FILTER command output displayed counters for 'passes' and 'include' that were the same. This issue has been resolved. Counters now increment only when a filter is active and do not count interface routes.

PCR: 02040

Module: SWI

Network affecting: No

PCR 02019 permitted the reception of packets by the CPU that should have been discarded. This issue has been resolved.

PCR: 02057

Module: FIREWALL

Network affecting: No

Firewall TCP timeout values have been reduced for sessions placed in the CLOSED state after receiving a TCP/RESET. This applies to the stateful inspection of firewall sessions only, and not to the TCP module. Previously, PCR 01263 reduced the timeout value for sessions placed in the CLOSED state after a TCP/FIN packet was received.

PCR: 02063

Module: FIREWALL

Network affecting: No

Firewall IP access lists were not working correctly. If an IP range was specified without spaces between the IP address and the separating '-' the range would be ignored. Spaces are no longer required. Also, matches were made to addresses covered by a range in an access list if the matching range was numerically the lowest in the list. This issue has been resolved.

Patch 86222-13 includes all issues resolved and enhancements released in previous patches for Software Release 2.2.2, and the following enhancements:

PCR: 02014

Module: TELNET

Network affecting: No

When a Telnet session was terminated without a proper logout, counters recording the number of logins were not correctly decremented. This issue has been resolved.

PCR: 02019

Module: SWI

Network affecting: No

If a layer 3 hardware filter for a particular packet type (e.g. Netbeui) was configured, all IP packets destined for the CPU were discarded. This issue has been resolved.
