HP 1920 ARP table size ?

hello everyone,

 

does anyone happen to know what's the HP 1920-48G's ARP table size?

I was only able to found its MAC table size [16k] but not the ARP one.

 

I'm I right if I take it like this: 16k for MAC table = 16k ARP table ?

 

thanks & cheers

Hello!

 

It's probably not 16k for the ARP table...

 

For exemple, for the 1910-48, the MAC table is 8k and the ARP table is 256 (I got problems with that...).

No, sorry. I didn't manage to find that in any HP document, only on forums...

And bigger switch than the 19xx have 256 entries too, so I wouldn't plan to do routing with a 1920...

If you dump the configuration of the switch it shows the ARP table size in the created file.

 

On our 1920-24g it is limited to 265 entries.

The 1920 can also route IPv6.  What is the IPv6 neighbor table size limit?

 

Compared to L2 MAC  CAM table size of 8192 , a max of 256 L3 hosts is pretty small.

Is there a command (in GUI or console mode) to devote a larger part of the ASIC switch fabric hardware to L3 functionality, sacrificing L2 MAC CAM table size?

 

On different brand switches, the command "sdm prefer" does this task.
