Patch 86231-10 For Rapier Switches and AR800 Series Modular Switching Routers 19
Patch 86231-10 for Software Release 2.3.1
C613-10328-00 REV J
If a packet with a destination IP address equal to a VRRP IP address was
received when the router didn’t own the IP address, (because it didn’t have
an interface with that IP address) the router incorrectly tried to forward the
packet and send an ICMP “redirect” message to the source. Now, if such a
packet is received, it will be discarded and an ICMP “host unreachable”
message will be sent to the source.
If a DNS relay agent was configured with overlapping subnets, sometimes
the DNS server response was returned to the client with a source IP address
of an interface of the relay agent that was different from the interface the
request was received on. This issue has been resolved.
When enabling or disabling feature licences, a message will now be
generated with a warning that changes to feature licences may not take
effect until after a reboot.
VRRP used the wrong source IP address in ICMP redirects. RFC 2338 states
that the source IP address of ICMP redirects should be the IP address that
the end host used when making its next hop routing decision. In the case of
a packet sent to a VRRP virtual MAC address, this is the primary VRRP IP
address associated with the MAC address, provided such a VR exists and is
in the master state. This issue has been resolved.
If IGMP and STP were enabled, and an IGMP packet was received on a STP
blocking port, the packet was forwarded to another port, causing an IGMP
storm. This issue has been resolved.
This PCR implements fan threshold control, parity enable/disable, A39 link
card enable/disable and Cell Buffer Pool Global Buffer Pool (CBPGBP)
enable/disable.
Some board names for the Rapier 24i and Rapier 48i were incorrect. This
issue has been resolved.
The SIZE functionality on the IP filter was not working for IP fragmented
packets. This issue has been resolved.
DHCP requests for IP addresses on incorrect and unroutable subnets would
fail. The DHCP server now offers an IP address on a valid subnet.
Layer 3 switch load balancing has been implemented across trunked ports.
