Yup. I MRTG graph both physical ports, and both inbound and outbound
traffic seems to flow over both interfaces. Have you configured the sun
trunking software correctly?
This is how my config looks:
On the cisco switch (relevant parts):
interface Port-channel2
description Port-channel to britt.qbranch.se
no ip address
no logging event link-status
switchport
switchport access vlan 4
switchport mode access
interface GigabitEthernet3/4
description Interface 1 of 2 for port channel 2 to britt.qbranch.se
no ip address
no logging event link-status
flowcontrol receive desired
switchport
switchport access vlan 4
switchport mode access
no cdp enable
channel-group 2 mode on
!
interface GigabitEthernet3/5
description Interface 2 of 2 for port channel 2 to britt.qbranch.se
no ip address
no logging event link-status
flowcontrol receive desired
switchport
switchport access vlan 4
switchport mode access
no cdp enable
channel-group 2 mode on
!
The cisco switch defaults to ip-source-dest address hashing for path
selection, so that's why it isn't mentioned above. Its a catalyst 6509
with SUP-1A running native IOS. Note that the port must be in mode "on"
for port channels. Suns software does not support auto negotiation of port
channels.
On the backup server, it looks like this:
In /etc/opt/SUNWconn/trunking/bin/nettr.sh:
# Add Sun Trunking Configuration entries below.
nettr -setup 0 device=ce members=0,1 policy=3
Then configure ce0 just as you would if it were a single interface. Note
that ce1 must not be plumbed.
Hope this helps. :)

Ps. Does anyone have an answer to MY question as well? :)
