Hi all,

  I have a SL6.1 server acting as a storage server (iscsi and nfs). Is 
it possible to configure jumbo frames on a specific vlan or is it a 
stupid question??

  This host has two physical nics, but in one of them I have configured 
vlans:

1: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast 
state UP qlen 1000
     link/ether 00:1f:29:55:92:b4 brd ff:ff:ff:ff:ff:ff
     inet 172.25.50.12/27 brd 172.25.50.31 scope global eth0
     inet6 fe80::21f:29ff:fe55:92b4/64 scope link
        valid_lft forever preferred_lft forever
2: eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast 
state UP qlen 1000
     link/ether 00:1f:29:55:92:b5 brd ff:ff:ff:ff:ff:ff
     inet6 fe80::21f:29ff:fe55:92b5/64 scope link
        valid_lft forever preferred_lft forever
3: eth1.10@eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc 
noqueue state UP
     link/ether 00:1f:29:56:44:6a brd ff:ff:ff:ff:ff:ff
     inet 172.25.60.3/28 brd 172.25.60.15 scope global eth1.10
     inet6 fe80::21f:29ff:fe56:446a/64 scope link
        valid_lft forever preferred_lft forever
4: eth1.20@eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc 
noqueue state UP
     link/ether 00:1f:29:56:44:6a brd ff:ff:ff:ff:ff:ff
     inet 10.1.1.5/27 brd 10.1.1.31 scope global eth1.20
     inet6 fe80::21f:29ff:fe56:446a/64 scope link
        valid_lft forever preferred_lft forever

  Can I assign mtu=9000 only to eth1.20??

Thanks.
