Hi
I need a kind help urgently.
I have 1 3560 switch connecting few servers. my server vlan is vlan 50.
i have many servers in this vlan among that for 2 servers i need to do load balanincing using microsoft load balanicng technology.
as per the documentation i see the commands and method to do this.
it is
arp <ip add> <mac address>
mac-add-table static <mac> vlan <vlan-id> interface <interface 1 interface 2>
but when i try to do the same in the 3560 it is not accepting the command -
arp <ip add> <mac address>
asking for <type>
I add type ARPA after that if i put ? can see fa interface, vlan, gig, port channel etc... also <cr>, what is this? what is the exact command syntax here?as of now i add it like this
arp 192.x.x.x 123c.xxxx.xxxx arpa
and
mac-add-table static 123c.xxxx.xxxx vlan 50 interface fa 0/1 fa 0/2
will it make any issue for the other servers in the same vlan ?
regards
Jacob

You don't need specify the interface.
Switch will find out which interface the packet should be sent out by searching mac table.

You would only need the 'arp' command if the 3560 is doing L3. Here are the configs you'll require:
arp 192.x.x.x XXXX.YYYY.VVVV ARPA alias
mac-address-table static XXXX.YYYY.VVVV vlan 50 interface fa0/1 fa0/2.
The important thing to note for is before you issue the command, have a look at the multicast counter under some interfaces on your switch. Clear the interface counter on all interfaces and configure the commands. Once configured, check that only fa0/1 and fa0/2 receive multicast traffic and no other ports on the switch.
The commands won't have any issue on the other servers.
