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).
