Enabling in-flight compression

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 452 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

Disabling in-flight encryption
Disabling encryption is an offline event. Ports must be disabled first, and then re-enabled after.
1. Connect to the switch and log in using an account with secure admin permissions, or an
account with OM permissions for the EncryptionConfiguration RBAC class of commands.
2. Disable the port using the portDisable command.
