Configuring MDS 9222i and portchannels

[larrywoods]

Trying to wrap my head around how a MDS 9222i is configured.  We have 2 of them and will be implementing FCIP.  I found a great document on FCIP and all of that and feel comfortable there.  However, connecting the MDS 9222i slightly confuses me.  I am assuming I can use all 4 of the 1Gbps copper ports.  Is this a correct assumption?  Can I use a portchannel/etherchannel configuration for this on the MDS?

Any help would surely be appreciated.  Thank you.

yes and yes   ..you can use all 4 Gige ports and port channel them together.

Ok fantastic.  I keep getting certain error messages when trying to configure the channel-group on the Gigabit ethernet ports:

interface port-channel 100

  channel mode active

  switchport description Core Link Connection

  switchport rate-mode dedicated

!

interface GigabitEthernet1/1

interface GigabitEthernet1/2

interface GigabitEthernet1/3

interface GigabitEthernet1/4

!

Switch(config-if)# channel-group 100

command failed: port not compatible [generic error]

** You can use force option to override the port's parameters

** (e.g. "channel-group X force")

Switch(config-if)# channel-group 100 force

command failed: port not compatible [generic error]

Switch(config-if)#

The 6500 configuration side is no problem but I can not seem to figure out how to configure the channel-group on the gig ports.  Any thoughts or configuration suggestions would be greatly appreciated.  Thanks.

i don't think you need to specify dedicated on gigE ports.

mds2(config)# interface port-channel 100
mds2(config-if)# channel mode active 
mds2(config-if)# switchport trunk mode on
mds2(config-if)# switchport trunk allowed vsan 10

Assuming you already build the four FCIP links

FCIP1, FCIP2, FCIP3, FCIP4

mds9222i# conf t

mds9222i(config)# interface fcip1-4

mds9222i(config)# channel-group 1 force

mds9222i(config)# exit

mds9222i(config)# interface po1

mds9222i(config)# no shut

mds9222i(config)# exit

mds9222i# show interface po1

you should have your port-channel 1 there

Good luck

Ok, you guys were on the right track but anyone else who comes across this issue there are some things that were not clearly noted (or maybe I read over them) posted here:

http://www.cisco.com/en/US/docs/switches/datacenter/mds9000/sw/4_1/configuration/guides/cli_4_1/clibook.html

Basically, MGMT port is required to get access to the device.  From there, I set up the gig ports which require separate IPs for each one that I want to uplink and for each FCIP configuration.

interface GigabitEthernet1/1

  ip address 10.123.10.201 255.255.255.0

  switchport description Core Link connection

  no shutdown

interface GigabitEthernet1/2

  ip address 10.123.10.202 255.255.255.0

  switchport description Core Link connection

  no shutdown

interface GigabitEthernet1/3

  no shutdown

interface GigabitEthernet1/4

  no shutdown

interface mgmt0

  ip address 10.111.2.200 255.255.0.0

From there, had to configure the FCIP connection:

fcip profile 1

  ip address 10.123.10.201

  tcp max-bandwidth-mbps 30 min-available-bandwidth-mbps 20  round-trip-time-ms 5

fcip profile 2

  ip address 10.123.10.202

  tcp max-bandwidth-mbps 30 min-available-bandwidth-mbps 20  round-trip-time-ms 5

interface fcip1

  use-profile 1

  peer-info ipaddr 10.198.10.201

  channel-group 1 force

  no shutdown

interface fcip2

  use-profile 2

  peer-info ipaddr 10.198.10.202

  channel-group 1 force

  no shutdown

Thats really it.  The default gateway needed to be on the same subnet/VLAN as the Gigabit interfaces NOT the mgmt interface.  Found that out the hard way but that wasnt a big deal to figure out.

From there, do the following command:

sho fcip sum

-------------------------------------------------------------------------------

Tun prof    Eth-if    peer-ip       Status T W T Enc Comp  Bandwidth   rtt

                                           E A A            max/min    (us)

-------------------------------------------------------------------------------

1   1    GE1/1      10.198.10.201    TRNK  Y N N  N   N       30M/20M  5000

2   2    GE1/2      10.198.10.202    TRNK  Y N N  N   N       30M/20M  5000

But that was it.  Thanks for the help.
