bonding howto FCX vs ICX


we are using a large number of FCX648 (running FCXS07400) and some new ICX 7450 (running SPR08030).

On the FCX we have some server attached using the TRUNK command.

trunk ethe 1/1/9 to 1/1/10 
 port-name "ServerXY_Trunk1" ethernet 1/1/9

How can I configure this on the ICX ? Is it something like:

lag SERVERXZ static id 7
 ports ethernet 2/1/41 ethernet 3/1/41
 primary-port 2/1/41 

Where are some example showing the advantage using static or dynamic "lag" ? Also for some OS would be very helpful.


Thanks a lot!

Bye, Peer

Inside the lag configuration on the ICX you need to enter a deploy statement:

lag SERVERXZ static id 7

A dynamic LAG uses control frames (LACP) to establish a relationship to a neighbor. The member port will only come up, when both sides run LACP and agree about an aggregated relationship.

Therefore traffic wont be lost, if you accidentally misconfigure a port or patch on a wrong device. In a static lag the switch is a little bit dumber and just blasts out on every possible interface.

The latest ICX Firmware 08.0.61 and later changes this again but for better:


There is no more "deploy" command or primary-ports, either.



lag NAME dynamic id 1
ports ethe 1/1/3 ethe 2/1/3



vlan 222 name SOME-Data by port
 tagged lag 1
 router-interface ve 222


=== LAG "NAME" ID 1 (dynamic Deployed) ===
LAG Configuration:

LAGS  are NOW actual virtual interfaces:


vlan 222 name SOME-Data by port
 tagged lag 3
 router-interface ve 222
interface lag 12
 trust dscp



They even track the aggregate speed correctly:



#sh int lag 1
Lag lg1 is up, line protocol is up
  Configured speed 2G, actual 2G, configured duplex fdx, actual fdx
  Member of 3 L2 VLANs, port is dual mode in Vlan 1, port state is Forward

  STP configured to ON, priority is level0, mac-learning is enabled

  Mirror disabled, Monitor disabled
  Mac-notification is disabled

It is also smart enough to switch you to the LAG interface.  For example:


SSH@Aggregation_Stack(config)#int e 1/1/27
