Image Deferral, Cisco IOS Release 11.3(8)T
Cisco IOS Release 11.3(8)T was deferred to Release 11.3(8)T1 on all software images to incorporate
corrections to the following caveats:
• CSCdk86294—The D channel is always in the shutdown state when non-facility associated
signalling is configured.
• CSCdk80809—Enhanced Interior Gateway Routing Protocol (EIGRP) has difficulty converging
on certain routes.
For more information on these caveats, see Bug Navigator II. Bug Navigator II is available at
http://www.cisco.com/support/bugtools or on CCO at:

Enabling IPX Routing
Whenever IPX routing is enabled, the Token Ring interface resets.
Forwarding of Locally Sourced AppleTalk Packets
Cisco’s implementation of AppleTalk does not forward packets with local-source and destination
network addresses. This behavior does not conform to the definition of AppleTalk in Apple
Computer’s Inside AppleTalk publication. However, this behavior is designed to prevent any possible
corruption of the AppleTalk Address Resolution Protocol (AARP) table in any AppleTalk node that
collects MAC addresses.
Missing Source-Route Bridging Commands
Due to a production problem, many source-route bridging commands were omitted from the printed
version of the Cisco IOS Software Command Summary (78-4746-XX). For documentation of all
source-route bridging commands, see Bridging and IBM Networking Command Reference
(78-4743-XX). You can also obtain the most current documentation on CCO or on the
Documentation CD-ROM.
