    on Catalyst 2900 series switch, the port which is connecting switch to
    the outside router suddenly started blinking orange. Everyone able to

    Please somebody help.

    duplex mismatch?

    do a sh int, look at number of collisions. Clear couters on interface then
    do sh int again. See if number of collisions is going up.

    there should be a mode button on the switch so that you can check

    I checked all those different modes. Everything looks good. And also
    checked for no. of collisions by using show interface. It showed so
    many no. of collisions (around 500,000).
    So I believe, only solution for decreasing the no. of collisions is
    increasing the bandwidth. Or something else can i do from my side??

    Actually the switch is configured to have only two VLAN. That's it
    nothing much complex configuration is used. So is it problem with

    I just now checked up for the duplex mode. Actullay it is in half
    duplex mode. So is it the real problem. Should i need to change it to
    Full duplex mode.

    As you said i did the clear counters on the interface and did the sh
    int. It showed me 69 collisions immediatley after clearing the
    counters. It is really issue of collisions because of half duplex
