Release Notes for Catalyst5000 Family Software Release4.x

OL-2306-01

Open and Resolved Caveats in Software Release 4.4(1)

• In some cases, after a switchover from the active (slot1) to the standby (slot2) supervisor engine,

the uplink ports on the previously active supervisor engine (slot1) fail to come online. You might

see this message:

%SYS-3-PORT_SSUPFAIL:Failed to bring up ports on standby supervisor

Workaround: Disable the standby ports using the set standbyports disable command and then

reenable them using the set standbyports enable command. If the ports still fail to come online,

reset the standby supervisor engine. (CSCdk73705)

• If a Catalyst5000 family switch is configured as a VTP client and its only connection to the VTP

server is through a port on the Gigabit EtherChannel module (WS-X5410) that is configured as an

IEEE 802.1Q trunk with its native VLAN other than VLAN1, when the system is reset the trunk

port might fail to enter trunking mode after the system comes online (the show trunk command

output shows the trunk in the “inactive” state).

Workaround: Reset the module on which the trunk port is located or set the native VLAN of the

trunk port to VLAN1. (CSCdk77956)

• In a Catalyst5000 family switch with redundant Supervisor EngineII modules and one or more

ATM modules, if you download a software image to an ATM module and the active supervisor

engine is reset before the ATM module comes online, the ATM image is corrupted and the output

of the show test command for the module shows “Flash-CheckSum Failure.” If you later reset the

ATM module again the system might generate this error message:

recv_data_active : errno = 60

followed by this error message every five seconds:

SYS-3:nvram_active unable to connect with standby

Workaround: Reset the system using the reset command and download the ATM image again.

(CSCdk79201)

• On the Catalyst5000 family Supervisor Engine III, make sure you have a cable attached to the

console port before entering the set system modem enable command. If you enter the command

with no cable attached, the switch might stop sending frames (including BPDUs) the next time an

event is reported to the console log. This might result in a broadcast storm, spanning tree loops, or
