2 Patch Release Note

Features in 86241-01

Patch 86241-01 includes the following enhancements:

PCR: 02036 Module: SWITCH Network affecting: No

A new command allows the Layer 3 aging timer to be changed:

SET SWITCH L3AGEINGTIMER=<seconds>

where seconds can be 30 - 43200. After each cycle of the ageing timer, all
existing Layer 3 entries with the hit bit set will have the hit bit reset to zero,
and all existing Layer 3 entries with the hit bit set to zero will be deleted.

The SHOW SWITCH command output now displays the Layer 3 ageing
timer value.

PCR 02138 Module: SWI Network affecting: No

The built in Self Test Code for all Rapiers, except G6, has been improved to
enhance the detection of faults in switch chip external packet memory.

PCR: 02158 Module: FIREWALL Network affecting: No

When a TCP RST/ACK was received by a firewall interface, the packet that
was passed to the other side of the firewall lost the ACK flag, and had an
incorrect ACK number. This issue has been resolved.

PCR: 02185 Module: VRRP Network affecting: No

The SHOW CONFIG DYNAMIC=VRRP command was not showing port
monitoring and step values correctly. This issue has been resolved.

PCR: 02229 Module: IPG Network affecting: No

The PURGE IP command now resets the IP route cache counters to zero.

PCR: 02240 Module: SWI Network affecting: No

The SENDCOS filter action did not operate correctly across switch
instances. This was because the stacklink port on the Rapier 48 did not
correctly compensate for the stack tag on frames received via the filter. This
issue has been resolved.

PCR: 02241 Module: FIREWALL Network affecting: No

Firewall subnet NAT rules were not working correctly from the private to
the public side of the firewall. Traffic from the public to private side
(destined for subnet NAT) was discarded. These issues have been resolved.
ICMP traffic no longer causes a RADIUS lookup for access authentication,
but is now checked by ICMP handlers for attacks and eligibility. If the ICMP
traffic matches a NAT rule, NAT will occur on inbound and outbound
traffic. HTTP 1.0 requests sometimes caused the firewall HTTP proxy to
close prematurely. Cached TCP sessions were sometimes not hit correctly.
These issues have been resolved.

PCR: 02242 Module: IPG Network affecting: No

On a Rapier 24, adding an IP interface over a FR interface caused an
ASSERT debug fatal error. This issue has been resolved.
