Increase mtu? How?

hi,

I setup:

- a LACP-trunk (aggr0) on two interfaces (ix0, ix1)

- two vlan interfaces over this trunk (vlan1002, vlan689)

- and a carp interface on each vlan interface

-- carp1 on vlan1002

-- carp2 on vlan689

I checked the hardware features:

ifconfig ix0/ix1  hwfeatures ... hardmtu 9198

ifconfig aggr0  hwfeatures ... hardmtu 9198

ifconfig vlan1002  hwfeatures ... hardmtu 9198

ifconfig carp1  hwfeatures  ... hardmtu 1500

Does it make sense to increase the mtu on the ix* interfaces when the 
mtu of then carp interfaces can't be set to a value greater then 1500?

Can other (future) vlans without carp benefit from a larger mtu on ix*?

When I try to set the mtu:

ifconfig ix0 down

ifconfig ix0 mtu 9180

ifconfig: SIOCSIFMTU: Device busy


Thanks in advance.


Kind regards

Thomas








Mit freundlichen Grüßen
