OmniSwitch 6600/7000/8800—Release 5.1.6.R02 page 73
PR 80494
On an OmniSwitch 6624/6648 switch, packets routed between IP-SNAP & Ethernet 2 are not translated
correctly. The Intel IXE2424 ASIC used in the 6600 platform does not support translations from SNAP to
Ethernet II packets.
Workaround: There is no known workaround at this time.
PR 81354
RIP task traps when more than 2K RIP routes are sent in the OS6600 Router from a RIP peer. This does
not always happen, and may occur very rarely even when the number of IP routes on the OS6600 Router
exceeds 2K. The trap happens due to a lack of memory allocation.
Workaround: There is no known workaround at this time. When the trap happens, the CLI console may
not be available for access and the OS6600 Router will reboot due to a lack of memory.
PR 84856
An OS6600 series switch learns the source and destination IP address of every forwarded flow, and has a
finite space (16K addresses) to store them; they have an aging time of 5 minutes. In certain kinds of DoS
attacks, the switch can run out of space to store these addresses, and this will affect routing of new flows.
Workaround: Use the clear arp-cache CLI command to cause the switch to delete most, if not all, of the
L3 addresses in hardware. All forwarded traffic will have to be re-learned.
PR 88951
On an OS7000 series switch, the IP interface is designed to be decoupled from VLAN management.
Therefore, deleting a VLAN doesn't remove the IP interface bound to the VLAN, it only makes the IP
interface inactive.
Workaround: There is no known workaround at this time.
PR 90083
On an OS7000 series switch, the IP Service Ports page in WebView is missing port 262, which corre-
sponds to avlan-http-proxy.
Workaround: Use IP Service Types page to enable or disable this service.
PR 92104
Webview or SNMP incorrectly shows the forwarding state of an IP interface as "forwarding", even though
the IP interface is administratively / operationally down.
Workaround: Use CLI to reflect the true forwarding status of an IP interface.
