    Hey,

     

    we have a 3 member 2930f stack and a problem between member 2 and 3. One port ist down and the other side is down with Error: Port speed mismatch. This is the vsf config:

     

     

    switch(config)# sh vsf


 VSF Domain ID    : 1
 MAC Address      : 089734-ab460b
 VSF Topology     : Chain
 VSF Status       : Active
 Uptime           : 1d 22h 7m
 VSF MAD          : None
 VSF Port Speed   : 10G
 Software Version : WC.16.07.0002

nsrb845k1(config)#

    We already tried another DAC cable but with no effect. Also set the vsf port speed to 10g.

     

    Kind regards

    Daniel

    A (sanitized, without S/Ns) show tech transceivers CLI Comman's output would help

    Why do you have some 1000SX interface ?

    the speed need be the same on the VSF.

    AFAIK...interfaces 1/49 and 3/50 don't play a role into his VSF deployment...so far, so good with those 1000SX interfaces.

    All other VSF involved ports are connected to DACs.
