%C6KPWR-SP-4-DISABLED: power to module in slot 4 set off (Reset - Module Reloaded
During Download)
%OIR-SP-3-PWRCYCLE: Card in module 4, is being power-cycled off (Reset - Module
Reloaded During Download)
%C6KPWR-SP-4-DISABLED: power to module in slot 4 set off (Reset - Module Reloaded
During Download)
%CWAN_RP-3-BOOTFAIL: The WAN module in slot 4/0 failed to boot
%OIR-SP-3-PWRCYCLE: Card in module 4, is being power-cycled off (Reset - Module
Reloaded During Download)
%CWAN_RP-3-BOOTFAIL: The WAN module in slot 4/0 failed to boot
%CWAN_RP-3-RESET_FAIL: The WAN module in slot 4 failed even after several resets
Workaround: Contact Cisco TAC for a workaround that prevents an RMA of the 7600-SSC-400.

Symptoms: The standby supervisor engine may crash when an interface has a stateful inspection
policy or when the ip nbar protocol-discovery command is enabled.

Conditions: This symptom is observed on a Cisco Catalyst 6500 series or Cisco 7600 series that run
a native Cisco IOS software image.

Symptoms: When MPLS cell-relay or ATM cell-switched traffic enters an OC-48 ATM SPA that is
installed in a SIP-400, the performance is limited to 64.5 percent of the OC-48 line rate (which is
about 1.5 Gb/s).
installed in a SIP-400, the performance is limited to 64.5 percent of the OC-48 line rate (which is
about 1.5 Gb/s).
Conditions: This symptom is observed on a Cisco 7600 series and occurs only for MPLS cell-relay
or ATM cell-switched traffic.
or ATM cell-switched traffic.
Workaround: Avoid sending MPLS cell-relay or ATM cell-switched traffic above 64.5 percent of the
OC-48 line rate to the OC-48 ATM SPA.

Note that the performance for two-cell traffic or traffic with larger packets (that is, non-cell switched
traffic) is not impacted and full line rate is supported in these cases.

Symptoms: When a hardware interface goes down, for example because the interface is shut down,
the cable is disconnected, or an uplink on a supervisor engine goes from the active state to the
standby state, packets in the egress direction are bridged in the software for later processing. When
there is a high traffic rate, this situation may cause CPU congestion until the routing table is updated
in the hardware. This type of traffic (that is, traffic that is bridged for later processing) cannot be
rate-limited.

Further Problem Description: The fix for this caveat causes the packets to be denied and dropped
instead of being bridged in the software.

Symptoms: When MLPoMPLS is configured, a VC comes up but, the first few ping packets from
one CE router to another CE router on the far end do not go through.

Conditions: This symptom is observed in a configuration with Cisco 7600 series routers that
functions as CE and PE routers.

Workaround: There is no workaround. Note that the connectivity recovers after a few pings.
