18 Patch Release Note
Patch 86222-22 for Software Release 2.2.2
C613-10319-00 REV U
The firewall was incorrectly forwarding multicast packets originating from
a private address in cases where a matching route was defined. This issue
has been resolved.
When the speed of one or more switch ports was forced to a half duplex
setting and the ports were then added to a trunk group configured for full
duplex operation, the port settings were not overridden by the trunk group
speed setting. The trunk group speed setting will now take precedence over
the port speed setting.
Configuring IP route filters did not stop flooding of AS external LSAs to
neigbours at startup. The result was that the neigbour received the AS LSAs
and added the corresponding routes into its own routing table. However,
after some time (e.g. 1 hour), the AS external LSAs in the neigbour’s
database disappeared, but the corresponding routes were still in its routing
table. This issue has been resolved.
The checksum in VRRP advertisements was not being calculated correctly.
The calculation was not compatible with the RFC. This issue has been
resolved.
When PPP was running over Ethernet to a client from another vendor, the
Maximum Transmission Unit value for the link was not adjusted from the
PPP default of 1500 to 1492. This issue has been resolved.
IGMP did not send the Start Up Query, and the Other Querier Present Timer
did not change the Time Out value accordingly if Query Interval was
changed. IGMP did not notify other registered parties (PIM and DVMRP)
when a port was deleted from a membership group. IGMP reported a
membership leave to other parties while it was still waiting for a reply to a
group specific query from a leaving member. These issues have been
resolved.
The timeout value for ICMP session entries in the firewall can now be
adjusted via the OTHERTIMEOUT parameter of the SET FIRE POLICY
command. Note: if the value for OTHERTIMEOUT is set to more than 10
minutes the timeout used for ICMP sessions will default to 10 minutes.
When a DHCP server received a DHCP DISCOVERY packet passed by a
relay agent, requesting an IP address that did not belong to the subnet the
client and the relay agent were attached to, it offered the requested address
if it was available. The DHCP server will now only offer an IP address from
the subnet that connects the client and the relay agent.
