Hi gurus! I need help

I have two interface ge0 and ge1

ge0 is for VLAN 1 and ge1 is for VLAN 2

I have no problems from server access from VLAN 1 and VLAN 2. the problem is when a server is accessing from a different VLAN ex VLAN 3. VLAN 3 is the same server farm as VLAN 2

The router broadcasts looking for the MAC address of the IP of ge1. from ifconfig I saw may ge0 and ge1 has the same "ether" entry. can I associate my ge1 to a different "ether"?

another possible problem is I only have one entry in defaultrouter . which is the router for VLAN 1. can I add the router for VLAN 2 to avoid flooding?

Thanks
 
Hi,

Since you have 2 nics and want each nic different mac address, I suggest you set "local-mac-address?" to true. Then reboot your machine.

dbase77's hint is the solution; for a quick test you can set the MAC using ifconfig command

daFranze,

how can I make sure that the MAC I will enter is unique?

dbase77,

I'll try that.

Thanks
 
this is the problem, you can't be sure!
BUT why not increase the MAC by 1 (I think this is default on a qfe NIC), I bet you don't have MAC+1 in your network...

daFranze,

If I use ifconfig to change the MAC address and the system reboot will the changes be in effect after reboot? or should I add something to rc.d. which file?

Thanks
 
no, changes with ifconfig are volatile, that's why I wrote "for a quick test you can set the MAC using ifconfig command"; I recommend to do what dbase77 suggested, too: set "local-mac-adress?" to "true", you can do this with the 'eeprom' command or shutdown the host and run 'setenv local-mac-adress? true' in ok Prompt...
