X440 48t-10G multiast table full

Ghezzi_Alberto — Tue, 13 Apr 2021 18:58:12 GMT

I have this problem, sometime the Multicast table are full, and i must do reboot the switch to clean the table. Is there another way to don’t reboot? Maiby acl?

Or have you other ideas?

The erros are these:

10:02:59 Kern.IPv4Mc: IPv4 multicast entry not added. Hardware L3 Table full. (Logged at most once per hour.)

09:19:15 Kern.IPv4Mc: Unable to Del L3 1:25 from s,G,v=a640102,effffffa,10 IPMC 2, unit 1 Entry not found

09:12:42 Kern.IPv4Mc: Unable to Del L3 1:25 from s,G,v=a640102,effffffa,10 IPMC 2, unit 1 Entry not found

09:01:57 Kern.IPv4Mc: IPv4 multicast entry not added. Hardware L3 Table full. (Logged at most once per hour.)

08:50:56 Kern.IPv4Mc: Unable to Del L3 1:20 from s,G,v=a640105,effffffa,10 IPMC 2, unit 0 Entry not found

Thanks a lot

Also:

Check if following CR's are applicable, the reboot is not a solution, it is a workaround and the issue will reappear after sometime again.

xos0060891 (While sending continuous join and leave as well as multicast streams multiple times allowing the streams to get aged out, the kernel error messages are seen for add/delete operation with reason "Entry not found")
- Fixed in patches released July 2015
xos0057375 (Multicast cache entries for local mcast group (i.e. 224.0.0.x/24) go out of sync)
- Fixed in 15.3.4,15.4.2.8-patch1-3 , 15.5.2,15.6.1 and higher

Thank you!

Not seeing the "config pim" option on the X440. As I am not savy with extreme os and product line is this switch able to be a querier / RP?

Hello!

Based on license level.

standard license for X440 - Edge - there is no PIM support
upgrade - Adv Edge - PIM-SM-Edge

PIM Edge Mode is a subset of PIM that operates with the following restrictions:
• The switch does not act as a candidate rendezvous point (CRP).
• The switch does not act as a candidate bootstrap router (CBSR).
• At most, four active PIM-SM interfaces are permitted. There is no restriction on the number of
passive interfaces (within the limit of the maximum IP interfaces).
• Only PIM Sparse Mode (PIM-SM) is supported.

Thank you!

I have standard license - EDGE.

Can you better explain about CRP and CBSR ?

I enabled only IGMP protocol .

Thanks
