ARP Often flush-out

 

Dear Folks,

 

                I'm facing issue here, as often ARP age-out in the time interval of 50 sec on particular vlan. Due to which that respective vlan servers are hitting with a impact.

                Here the ARP age-out is configured default as per the NX-OS its 1500-sec (25-min). On contrary other vlans are doing good with their default age-out timer, as they have the flushing on XX mins. Only this vlan is going weird with flush time of 50 sec even though its 1500 as default.

                Seeking on your suggestions.

 

N7K-switch# sh ip arp vlan 2

Flags: * - Adjacencies learnt on non-active FHRP router
       + - Adjacencies synced via CFSoE
       # - Adjacencies Throttled for Glean
       D - Static Adjacencies attached to down interface

IP ARP Table
Total number of entries: 6

10.0.0.4  00:00:11  bxx0.5bd0.7752  Vlan2

Thanks . . .
