Ping Drop issue in SG500 and ARP table full

[susamghatak@gmail.com]

I have 29 quantities of sf300 as L2 switch and one SG 500(L3), all inter-vlans routing through SG500, but recently I saw some pings drop on inter VLAN(after 100 more computers added on network), there is no issue with same VLAN. In inter VLAN ping time is 2ms or sometimes 30ms and some ping drop issue. Even in logs it is showed ARP table overflow. I have attached some screenshots,take a look. Please tell me what to be, should I increase TCAM if yes, what should it be? Total numbers of ip devices(Computer, IP-phone,Server,laptop,mobile etc) is 1200

Hi

Could you try to re-upload the tcam utilization tab?

The image you uploaded didn't show anything.

[susamghatak@gmail.com]

Yes , I am sorry I have uploaded wrong file. Here is the jpeg.

Thanks. I thing you should increase the amount of TCAM entries for you IP routing to a bit more than the number of total hosts.
That being said you should create a plan to upgrade the switch to another model since the mac TCAM entries are 2k. If you plan to keep adding hosts to your network.

So what should be the highest number for TCAM in SG500. Please suggest the
exact number to put.

Here is the TCAM status.

Where?

Try putting the max allowed(1996), and see what happens. But do it in a test environment or in a service window. The switch might need to reboot for the change to take effect.

And don't blame me if stuff stops working during the test:)

What should the number 1996 is not taken.
