Maximum ARP Cache Entries for ISRg2 1921 and 887VA Devices

[canero]

Hello,

We are looking to find the number of maximum ARP Cache Entries for 1921 and 887VA series Routers. Do they go upto a limit that memory allows, or is there a maksimum arp cache entry limit for both of the router types?

Thanks in Advance,

Best Regards,

Hi,

ARP limit should be system wide, distributed systems like 12000 or CRS may have a copy of ARP table on linecards

For what scenario/application are you looking for these data?

Hello Latchum,

There may be a large number of hosts for the Vlan that 1921 and 887 is residing, so it is important to know if this number is more than 2000,

Hi,

It could be more than 2000 but still it depends on the system resources like mem and cpu.
