Patch 86222-27 For Rapier Switches 9
Patch 86222-27 for Software Release 2.2.2
C613-10319-00 REV Z
Features in 86222-24
Patch file details are listed in Table 4:
Patch 86222-23 includes all issues resolved and enhancements released in
previous patches for Software Release 2.2.2, and the following enhancements:
When a NTP packet was received from an NTP server (mode 4) the router
acted as a client, and sent a reply back to the server, but did not remove the
peer association. This meant that the Dynamic Peers list, viewed using the
SHOW NTP command, displayed incorrect dynamic peer associations. This
issue has been resolved.
Previously, when Firewall or IP NAT was enabled, any fragmented IP
packets had to be reassembled so they could be processed. If the fragments
could not be reassembled, the packet was dropped. Reassembly could only
occur if the combined packet (IP header, and protocol header, and data) was
no more than 1800 bytes. An additional limit of no more than eight
fragments was also imposed. This PCR implements enhanced fragment
handling for Firewall and IP NAT. Each module can now be configured to
process fragmented packets of specified protocol types without needing to
reassemble the packet. The number of fragments a packet may consist of is
also configurable. This enhanced fragment handling is disabled by default.
To enable enhanced fragmentation for Firewall, use the command:
ENABLE FIREWALL POLICY=policy_name
FRAGMENT={ICMP|UDP|OTHER}
To enable enhanced fragmentation for IP NAT, use the command:
ENABLE IP NAT FRAGMENT={ICMP|UDP|OTHER}
To disable enhanced fragmentation for Firewall, use the command:
DISABLE FIREWALL POLICY=policy_name
FRAGMENT={ICMP|UDP|OTHER}
To disable enhanced fragmentation for IP NAT, use the command
DISABLE IP NAT FRAGMENT={ICMP|UDP|OTHER}
To configure the number of fragments permitted per packet for Firewall, use
the command:
SET FIREWALL FRAGMENT=8...50
To configure the number of fragments permitted per packet for IP NAT, use
the command:
SET IP NAT FRAGMENT=8...50
