Questions with the arp values in the Exos datasheet.

Hi Sirs

I have some questions for exos datasheet .

What is the value of ARP table on the datasheet ?

I just only watch IPv4 Hosts: - with min LPM IPv4 entries: 72K max

but on the releasenote .it shows 74,000 as below picture

If calculating 1 k = 1024, then 72 k becomes 72 x 1024 = 73 728, close to 74 000. I suspect that may be the reason. If you are anywhere near that limit, you may well bump into problems even before the limit as the hashing of MAC entries is rarely evenly distributed. If you need more than 60 k MACs, talk to your Extreme SE about it.

show forwarding hardware-utilization can show you how utilized the various tables are.

configure forwarding internal-tables more l2 configures the switch to allocate more room for L2 MAC at the expense of L3 entries.

Sorry, didn't read properly. You want more L3 space and probably can spare some L2 entries. You probably want this:

configure forwarding internal-tables more l3-and-ipmc
