Arp Table Size - A5120Si

[Yobaaa]

Hi

Please help me:

In our network i determine what A5120Si (used as core) learning only 256 ARP entries summary for all interfaces(vlan1,vlan2....) and displayed "ARP table is full and number of items is 256", but as far as I know A5120Si must learning 256 ARp entries for each interface. How i can configured it?

The 256 ARP limit is per the whole box, not per interface.

256 at all in the Switch?

while to understand this:

#
interface Vlan-interface1
ip address 192.168.254.100 255.255.255.0
dhcp select relay
dhcp relay server-select 1
arp max-learning-num 256
#
interface Vlan-interface2
ip address 192.168.1.100 255.255.255.0
dhcp select relay
dhcp relay server-select 1
arp max-learning-num 256

Yes, it´s  256 per switch, the same as HP 1910. No, I do not know any possibility to raise that. If you need more, you have to buy another switch...

Yes, per the whole switch. The arp max-learning-num command is to limit the number or ARPs learnt per interface, but you still can't go over the 256 limit that is switch-wide.
