Hi ,

Could some one explain whats the difference between the using the port and using the Any while configuring VIP on CSM?

After configuring "Any" keyword under the context the application is not  working.

(NOTE: If I change it to http it works eg:virtual tcp http/port  number)


vserver usa

virtual tcp any  :-----If i change this "any" keyword with  tcp  port number it works

  replicate csrp sticky

  replicate csrp connection

  no persistent rebalance

  slb-policy fariha


policy fariha

sticky-group 4

serverfarm zain

sticky 4 cookie zain insert

The IOS running on the CSM is 2.2(3)

Any help would be appriciated.

The "tcp any" will allow connections to that Virtual IP on any TCP port.  If it is

working using the specific port, it should be working using any.  Keep in mind that the CSM will accept and load balance using "tcp any," b

ut your server may not be listening on that port and will reset the connection.

As a best practice, you should define the specific port on the vserver for load balancing.  Using the "any" statement has it's purposes, but for general load blancing define the tcp/udp port number for your application.  This is also more secure.
