Multicasting problems

[j.lipsett]

I have 6506 switches with MSFC as the Distribution switches and a mix of cat 3550 and 4506 as access switches. We have just started the migration from NT to XP using Ghost software(Multicast). the site has multiple vlans and the MSFC is configured for Ip multicasting and on the vlan interfaces pim dense-mode and CGMP. on the access switches I configured IP IGMP Snooping. This works well on the 3550 switches, but we seem to be having problems rolling out the new image where there is a 4506 switch(IOS 122(18)EW2), very slow?. Has anyone came across this issue.

Hello,

do you see any errors on the trunk ports (assuming you are using trunks) connecting the 4500s and the 6500s ? Are the 4500 trunks configured in the same way as the 3550 trunks ? Is traffic on the 4500s slow for the ´ghosted´ machines, or for other machines as well ? You might want to check CPU utilization on the 4500.

Regards,

GP

Hi GP

All are dot1q trunks and native vlans set, full duplex Gigabit. I'll check on Monday for errors on the trunks. the funny thing is, that the first time on one of the 4506 it work ok, because one of the others did not work well we tried it again on the first 4506 and it did not work well? tried higher and lower versions of IOS, same thing happened. \again no problem with the 3550's.

No errors on trunk ports or server port, all trunks are configured dot1q full duplex 1000. Only ghost application affected. CPU ok
