SHOW IGMPSNOOPING ROUTERADDRESS

Patch Release Note

Patch 86253-07 for Software Release 2.5.3

C613-10382-00 REV E

When adding a port to a VLAN, any STP ports that had been disabled in the 
default STP were re-enabled. This issue has been resolved.

When the DELETE DHCP RANGE command was executed, DHCP 
attempted to reclaim the addresses in that range. It also tried to reclaim 
addresses in that range that were not allocated at that time, resulting in 
duplicate addresses appearing on the free list for allocation. This has been 
resolved by allowing DHCP to reclaim only those addresses that are 
currently in use by one of its clients.

When changing from RSTP to STP mode, the STPCOMPATIBLE option for 
the RSTPTYPE parameter incorrectly appeared in the dynamic 
configuration. Also, when changing from RSTP to STP mode or vice versa, 
disabled STP ports did not remain in the disabled state. These issues have 
been resolved.

If a port went down, the port was deleted from the appropriate static IGMP 
associations but was not added back again when it came back up. Similarly, 
static IGMP associations were automatically deleted but not added back 
when IP or IGMP was disabled. These issues have been resolved. You can 
now create IGMP associations before enabling IGMP, and they will become 
active when IGMP is enabled.

The maximum number of firewall sessions had decreased since software 
release 86s-241. This issue has been resolved.

Previously, an incorrect source address was used for router advertisements 
that were sent over an IPv6 tunnel. The source address of the tunnel 
(specified by the IPADDRESS parameter of the ADD IPV6 TUNNEL 
command) was used instead of a link local address. This caused an 
interoperability problem, which has been resolved. Now, if the specified IP 
address is not a link local address, then a link local address will be created 
based on the IPv4 tunnel source address and used for router 
advertisements.

If a ping was active and the IP configuration was reset, subsequent pings 
were sent out the wrong interface. This issue has been resolved.

Executing a ping to the IP address 0.0.0.0 did not return an 

invalid 

destination address

 error message. Also, when the TRACE command 

was executed for local addresses, it timed out after 90 seconds. These issues 
have been resolved.
