Upgrade and downgrade considerations
Table 58describes the upgrade and downgrade considerations for EX_Port Frame Trunking.
Using EX_Port Frame trunking
With EX_Port frame trunking, you can use the same CLI commands as you do for E_Port trunking.
Security considerations
Administration control for EX_Port trunking is available through root, admin, and switch admin access.
Trunking commands
The procedure for administering EX_Port frame trunking is the same as for E_Port trunking. You will need to
initialize trunking on ports with portCfgTrunkPort or switchCfgtrunk, monitor traffic with the
portPerfShow command. You need a Brocade license to enable trunking, however, you can disable
trunking on the ports without the trunking license installed. You can use the following commands to enable
and disable trunking:
Disable (0) or enable (1) trunking on a single port using the portCfgTrunkPort command. The
following example shows how to disable trunking on a single port and then how to enable trunking:.
Disable (0) or enable (1) trunking on all the ports of a switch using the switchCfgTrunk
command.The following example shows how to disable trunking on all ports and then how to enable
trunking:
When either command is executed to update the trunking configuration, the ports for which the
configuration applies are disabled and reenabled with the new trunk configuration. As a result, the traffic
through these ports might be disrupted for a short period of time. In addition to the commands for enabling
and disabling trunking, you can also use the following E_Port commands for administering EX_Port Frame
Trunking:
Use portCfgSpeed and switchCfgSpeed to set speed for a port or switch
Display lists of trunks and members of trunks with the trunkShow command
Use trunkDebug to list link characteristics for troubleshooting.
Use the switchShow command to display the trunking information on the EX_Ports.
For details about using these commands, see the Fabric OS Command Reference Manual.
Table 58 Trunking upgrade and downgrade considerations
Upgrade or downgrade Consideration
A firmware downgrade from Fabric OS
v5.2.x to Fabric OS v5.1.0
If EX_Port trunking is on, prior to the firmware downgrade, the
script displays a message requesting that you disable EX_Port
trunking.
A firmware upgrade from
Fabric OS v5.1 to Fabric OS v5.2.x
The trunking feature is turned off for each EX_Port configured on
the FCR switch. To explicitly enable trunking on all/one
EX_Port(s), you can use the portCfgTrunkPort and
switchCfgTrunk commands. See the following sections for
examples.
switch:admin_06> portcfgtrunkport 1/10 0
switch:admin_06> portcfgtrunkport 1/10 1
switch:admin_06> switchcfgtrunk 0
switch:admin_06> switchcfgtrunk 1
Configuration applied to all ports except the following VE/VEX_Ports (ports 128 -
143, 192 - 207).
