Upgrade Considerations

When you upgrade to SLX-OS 20.1.1 and later, warning messages capture the difference between the new TCAM profiles and the TCAM profiles in the version from which you are upgrading.
The deprecated profiles and the Layer2-optimized profile are not supported in SLX-OS 20.1.1 and later. When the warning messages appear, press n to cancel the upgrade and choose a supported TCAM profile.
For the supported TCAM profiles, you can remain in your current profile (press y in the warning message) or choose a different profile (press n) based on the recommendation in the warning message.
If you change a TCAM profile based on the recommendation, then the warning message for the new TCAM profile will not be displayed during the upgrade restart.
If you press n to cancel the upgrade and choose a supported profile, you need to save the TCAM configuration before restarting the upgrade.
Renamed TCAM profiles are automatically converted to the new profile after the upgrade.
The warning messages describe the feature parity between the new and old profiles.
You cannot change a TCAM profile after running the MCT script. You have to wait to change the TCAM profile after the upgrade is complete.
If you change a profile before starting the upgrade (by means of the firmware download command) and the upgrade then fails, you must manually change the profile back to the previous configuration.
For renamed, merged, and deprecated profiles, you need to save the running-config to the startup-config after the upgrade is complete.

Sample Warning Message to Remain in the Current Profile

Performing system sanity check ...
Warning: The current TCAM profile is 'default'. This profile does not support VNI Match 
for IPv4 ACL, VRF Match for IPv4 BGP-Flowspec rules, SA port authentication, VM Tracking, 
LOAM Loopback, and DSCP remarking in SLXOS version 20.x.x. The scale limits for ACL will be 
reduced to 4K (MAC + IPv4) and for MPLS-XC-Stats will be reduced to 256. Rules above new 
scale limit will not be effective after upgrade to SLX version 20.x.x.

You are running firmware download with 'fullinstall' option.
This command will preserve startu-config file and license file across firmware download and 
auto-replay configs. 
This command will cause a cold/disruptive reboot and will require that existing telnet, secure 
telnet or SSH sessions be restarted.

Sample Warning Message with a Recommended Profile

This example includes the selection of a new profile and the restart of the software download process.

Performing system sanity check ...
Warning: The current TCAM profile is 'vxlan-ext'. This profile does not support MCT in SLXOS
version 20.1.1. The recommended TCAM profile is 'default'. Please run the 'profile tcam'
command to change the profile to 'default' to retain the MCT support else proceed normally.
Note that if 'default' profile is chosen, VXLAN visibility ACL is not supported, ACL scale limit
will be reduced to 4K (MAC + IPv4). The ACL rules above 4K will not be effective after upgrade to
SLX version 20.1.1.
