Enabling in-flight compression
Enable in-flight compression to provide better bandwidth use on the ISLs, especially over long
distance. Frames are compressed at the egress point of an ISL and then decompressed at the ingress
point.
Enabling compression is an offline event. Ports must be disabled first, and then re-enabled after.
Before performing this procedure, it is recommended that you check for port availability. Enabling
compression fails if you try to exceed the number of allowable ports available for encryption or
compression on the ASIC. Refer to
Viewing the encryption and compression configuration on page
414 for details.
1. Connect to the switch and log in using an account with admin permissions, or an account with OM
permissions for the SwitchPortConfiguration RBAC class of commands.
2. Enter the portDisable command to disable the port on which you want to configure compression.
3. Enter the portCfgCompress --enable command to enable compression.
The following example enables compression on port 15 in slot 9 of an enterprise class platform:
switch:admin> portcfgcompress --enable 9/15
4. Enter the portEnable command to enable the port.
After enabling the port, the new configuration becomes active.
The following example enables compression on port 0.
switch:admin> portdisable 0
switch:admin> portcfgcompress --enable 0
switch:admin> portenable 0
You can verify the configuration using the portCfgShow command.
switch:admin> portcfgshow 0
