Multicast Traffic drop?????

I am losing some of the multicast traffic in/between Router, switch, and DB and would like to know if I am losing them in a router or not.  Also I would like to get some recommendation what kind of switch to buy for multicast traffic.

These interfaces look really clean and what you are receiving is what you are sending.  Is this router configured with pim or igmp?

ASKER

it's configured with pim dense-mode

interface GigabitEthernet0/1
 ip address 192.x.x.x 255.x.x.x
 ip pim dense-mode
 load-interval 30
 duplex full
 speed 1000
 media-type rj45
 no negotiation auto


interface GigabitEthernet0/3
 ip address 130.x.x.x 255.x.x.x
 ip pim dense-mode
 load-interval 30
 duplex auto
 speed auto
 media-type rj45
 no negotiation auto
What does the switch interface show with regard to packets coming from the router/

it's about 10 years old 3Com switch and it's not accessible from office.  I will be going to the data center tomorrow to check the switch interface.  Do you have a good recommendation for a switch?  I am thinking Cisco Catalyst series so I can manage it from office.

thanks
Cisco is good.  I also like Brocade's FCX.  The syntax is very cisco-like except that in cisco world, you put the interfface in a vlan and on the fcx you put identify the interfaces under the vlan portion of the config.

_jesper,

What should I look for in a switch?

Your considerations are:

   1) gigabit capable
   2) copper or fiber (or both)
   3) the total number of ports needed
   4) redundancy or spares
   5) managed (this is mandatory for me)
   6) layer 3 (routing) functionality

If budget is an issue, consider purchasing a refurbished (sometimes also new in box).  I prefer Network Hardware.  Their product is reliable.

Jasper,

Thanks for the recommendation.
I am in data center and what should i check from switch for multicast drop???
I checked all the port status and no drop.
