Multicast Problem?

[nevets2001uk]

Hi,

I know nothing about switching except the absolute basics and am hoping someone here may be able to help me out. We are having problems with some PC we have set up that connect to a novell network. These problems include taking a long time to find the tree after booting and network dropouts etc.

One suggestion that was made was that it could be down to switching. This seems possible since they work fine in our office which connect straight onto the main cisco Catalyst 4506 switch through an old unmanaged switch. The problem occurs once they are out in the main offices connecting through Cisco 2950 switches.

Looking into this problem it was suggested it could be due to the switch and the way it deals with IGMP protocols 779-934966.

How could I check this and possibly configure the switch to work correctly. Having never done this before I'm lost!

Cheers.

Make sure that host ports (computer workstations) are set to "spanning-tree portfast" on the Cisco switches. Don't set the switch to switch port though.

Thanks baddos. How would I go about doing this? I'm afraid I have no experience with switch configuration at all!

If you telnet into the switch or connect via the serial port, you need to do the following.

enable
!Might need to enter a password
configure terminal
   interface fastethernet0/1 !assuming this is a host/compupter port
      spanning-tree portfast
