" Extension Mobility Login Unavailable (22) "
When configuring extension mobility for a Call Manager environment. Generally when getting the above error you need to enable EM under the actual device.
If you're looking at a switch and you see the HULC LED Process running high. The HULC LED process does some of the following tasks: 1. Check link status on every port 2. If the switch supports POE, it checks to see if there is a power device 3. Transceiver checks 4. Fan status updates 5. Set LED ports 6. Check on temperature status Overall the HULC LED Process is a monitoring process running. During looking into this I turned off all non-used ports since it checks the link status. Then I made sure the environment was good.

%PLATFORM_UCAST-4-PREFIX: One or more, more specific prefixes could not be programmed into TCAM and are being covered by a less specific prefix, and the packets may be software forwarded So what is TCAM ? Ternary Content Addressable Memory is used in multi-layer switching also know as Layer 3 switching. The switches forward the packets and frames at the speed of the line by using ASIC hardware. Normally switches make there forwarding decisions based on Layer 2. TCAM is used for Layer 3 components and other features such as QOS and ACES ( Access List ). Check TCAM and usage of templates being used in the device. show sdm prefer ? ! This will show us the templates that can be used in the device to give more resources to one feature or the other. For example the default is the equal resource distribution while the routing gives more resources to Layer 3 routing. show sdm prefer ! The command without the "?" will show us what we are currently r
