BUFFERMANAGER Messages
BUFFERMANAGER Messages
This section contains the memory buffer management (BUFFERMANAGER) message.
Error Message C4K_BUFFERMANAGER-3-OUTOFVBUFS: Have run out of vbufs (internal
buffers)
Explanation
The switch ran out of the internal memory buffers that are used for various tasks. This
error is unusual because the internal buffers are used for only a short time, released, and then
available for reuse. Typically, this condition is transitory.
Recommended Action If the message persists, reboot the switch.
CHASSIS Messages
This section contains the chassis (CHASSIS) messages.
CHASSIS-2
Error Message C4K_CHASSIS-2-ALLCHASSISSEEPROMSINVALID: Contents of all chassis's
serial eeproms are invalid
Explanation The contents of all of the chassis's serial EEPROMs are invalid. In non-redundant
chassis, there is one serial EEPROM, and it is bad. If this is a redundant chassis, there are two serial
EEPROMs, and they are both bad.
Recommended Action Try removing and reinserting the supervisor engine. If that doesn't work, try
power cycling the switch. If the serial EEPROM is still invalid, this chassis should be returned.
Error Message C4K_CHASSIS-2-SUPERVISORSEEPROMINVALID: Contents of supervisor's
serial eeprom are invalid
Explanation
The contents of the supervisor engine's serial EEPROM are invalid. For example, a bad
checksum or the supervisor engine type doesn't match with the other hardware information. This
could happen if the read failed because the supervisor engine isn't seated correctly in the slot.
IOS considers this supervisor engine faulty and will not bring up the chassis' interfaces.
Recommended Action Try removing and reinserting the supervisor engine. If that doesn't work, try
power cycling the switch. If the switch still fails to come online, this supervisor engine should be
returned.
