14 Release Notes for Cisco uBR904 Cable Access Router for Cisco IOS Release 11.3 NA

Caveats for Release 11.3(1) through 11.3(10)NA.

IP Routing Protocols

• CSCdm20483

IP access lists fail to block pings on the interfaces conﬁgured for policy routing with IP

route-cache policy.

• CSCdm28898

ARP to a router fails on the serial interface when bridging is enabled and after the router is

reloaded.

----eth---2500---serial---2500---eth---

Router : 2500 IOS : 112.(17), 12.0(3.7)

Workaround: Remove IP address on serial and enter again.

• CSCdm44957

Some IP fragments may be incorrectly ﬁltered out by access lists.

• CSCdm53317

DNS replies passing from "inside" to "outside" through NAT are not NAT translated correctly in

many cases. There is no work around.

Miscellaneous

• CSCdk45491

Symptom: The NM-1FE-TX fails to autonegotiate properly when connected through an SMF

connector.

Analysis: Manually setting the speed to 100 solves the problem. An interface speed command

with the following syntax is being added to overcome this. The default behaviour would be to

autonegotiate:

[no] speed {10 | 100 | auto}

• CSCdm18910

When port info is passed from LAC and ’vpdn aaa attribute nas-port vpdn-nas’ is conﬁgured, it

should be mapped to the correct NAS-Port-Type value.

• CSCdm22032

Conﬁguring ppp encaplusation on an interface and making that interface a member of a bridge

group gives “tracebacks” and “fair-queue not initialized properly” messages. Remove bridging

from the interface or turn off fair queueand the massages dissappear.
