Symptoms: Accounting start sent on DHCP OFFER rather than ACK.
Conditions: This issue can cause accounting irregularities if the DHCP process does not complete.
For example, with active-active Cisco Intelligent Services Gateway (ISG) redundancy, two DHCP
OFFERs will be sent, but only one will be accepted. Since accounting records are generated for both
OFFERs, they will be duplicates of each other.
Workaround: There is no workaround.

Symptoms: Cisco 7600 router has multiple E1s that randomly flap.
Conditions: Occurs on a router with RSP720, SIP-200 and 8xCHT1/E1 SPA installed.
Workaround: There is no workaround.
• CSCsw52698
Symptoms: The following error message is displayed:
%BACKPLANE_BUS_ASIC-4-DEV_RESET: Backplane Bus Asic reset, interrupt
[0x062D]=0x0008
Conditions: Symptom reported by 7600-SIP-400 cards on 7600 Series Routers when PPPoE
connections are terminated via the 7600-SIP-400 cards.
Workaround: There is no workaround.
• CSCsw70125
Symptoms: A Cisco 7600 SIP-400 with POS interfaces encapsulated with IETF frame-relay may
incorrectly set 0x800 as Network Layer Protocol Identifier (NLPID) for hardware assisted multicast
IP packets. The correct value is 0xCC.
Conditions:
A. IP unicast packets in hardware path do not have this problem.
B. IP multicast or unicast packets in software path do not have this problem.
C. Problem reproducible in Cisco IOS Release 12.2(33)SRA2, 12.2(33)SRA7, and 12.2(33)SRC2.
Workaround: There is no workaround.
• CSCsw71208
Symptoms: Cisco 7600 does not respond properly to Link Control Protocol (LCP) echo requests,
causing PPP sessions to renegotiate between the router and non-Cisco devices.
Conditions: Occurs on a Cisco 7600 running Cisco IOS Release 12.2(33)SRC2.
Workaround: Disable keep-alives on the non-Cisco device.
• CSCsw73956
Symptoms: During health monitor failure, platform action was taken immediately but platform
action should be taken from gold TCL policy.
Conditions: Occurs when health monitor test failure crosses failure threshold.
Workaround: There is no workaround.
