Caveats for Cisco IOS Release 12.0
78-6455-12
Resolved Caveats—Cisco IOS Release 12.0(5)
• CSCdm48450
When stac compression is enabled on RSP routers configured for bridging with HDLC
encapsulation, the router is unable to pass traffic.When checking the start of the HDLC packet to
determine if it is a bridged packet board, encapsulations are not taken into account. Because of this,
HDLC_BRIDGECODE is not read correctly.
Workaround: Disable compression.
• CSCdm54100
Autoselect functionality does not exist in Cisco IOS Release 12.0 prior to Release 12.0(6). There
is no workaround.
• CSCdm57650
In Multi-chassis MLP stack group, when two stack group member cross project MLP link
interfaces. One of the stack group members might crash. There is no workaround.
• CSCdm58462
When LANE clients are configured with more than 14 HSRP groups per subinterface, along with
Multiprotocol over ATM (MPOA), a Cisco router might reload due to insufficient buffer space for
carrying all the HSRP MAC addresses. There is no workaround.
• CSCdm59077
If you upgrade to Cisco IOS Release 12.0(3)T, AIP might not properly recognize the “Burst size in
number of 32 cell bursts” option configured under the interface:
7513#conf t
7513(config)#int atm 1/0.1 point
7513(config-subif)#atm pvc 1 1 100 aal5snap 25000 10000 ? <b> <1-63> Burst size in number
of 32 cell bursts</b> inarp Inverse ARP enable oam OAM loopback enable <cr>
7513(config-subif)#atm pvc 1 1 100 aal5snap 25000 10000 <b>1</b> Invalid burst size of
1 cells requested: (ATM1/0): Not creating vc:1:1:100
7513(config-subif)# </pre>
There is no workaround.
Resolved Caveats—Cisco IOS Release 12.0(5)
All the caveats listed in this section are resolved in Cisco IOS Release 12.0(5). This section describes

Access Server
• CSCdm09417
A Cisco AS5200 access server might not be able to dial out using channel associated signaling
(CAS). This condition occurs intermittently. There is no workaround.
• CSCdm21149

No response is received from the server (Cisco AS5800) modem, even though the modem connects
successfully. There is no workaround.
