Re: Switch 2950 errors

Hello,

the following bug might apply. The ´workaround´ is to return the switch to Cisco and have them ship a new one to you:

CSCdv83336 Bug Details

Under certain level of traffic load, the (2950) switch will start logging the

following messages on the console:

SCHAN ERROR INTR: SRC=6 DST=5 OPCODE=20 ERRCODE=5

and after a few seconds, the switch will stop passing any traffic. In some

cases, the switch seemed still forwarding broadcast and multicast traffic,

which will cause STP problem if the switch has redundant link and is not

supposed to be the root for the VLAN, as both port will go forwarding.

The same error message has been identified in CSCdu87836.

An assessment of the impact

Unit stops passing any traffic.

WORKAROUND

Several units were returned by CISCO. The units were re-screened to the

latest test program, and failed the SDRAM memory test.

Regards,

GP
