SG300 DAI LIST only 128 entries

[lipengcisco]

i have a SG300-28,i  try to config the DAI of vlan,i found that only 128 can be config in the DAI list.As follow:

SG300-9F(config)#ip arp inspection list creat test7

SG300-9F(config-arp-list)#ip 172.16.32.254 mac-address 0024.9787.04ff

.

.

.

SG300-9F(config-arp-list)#ip 172.16.32.75 mac-address 206a.8a7f.d16b

SG300-9F(config-arp-list)#ip 172.16.32.253 mac-address 206a.8a5d.e303

ARP Inspection cannot be enabled. Resource is unavailable.

but i read the document of officer it's said DAI list could be contain 1024,i don't know why i can't defined more IP/MAC entries.

Hi Peng, I found in the documentation it does say 1024. However, I am only able to use 128 ip/mac addresses using 1 list or if I make several access lists. I will file a ticket with Cisco for this.

thanks for your help.

I read the documentation offered in this address:

http://www.cisco.com/en/US/products/ps10898/prod_maintenance_guides_list.html

and  page 321 of this documentation said:

Up to 1024 entries can be defined in the ARP Access Control table.

One vlan one DAI list,but actually i need more than 128 of list for every vlan in SG300,so that's what confuse me.
