WiMAX Debug Commands
The following are the WiMAX exec debug commands:
• clear interface wimax interface name statistics
• debug wimax pm {all | demux | deque | error | event | trace | warning}
Checking Signal Strength
If the Received Signal Strength Indication (RSSI) level is very low (for example, if it is less than -110
dBm), follow these steps:
Step 1 Check the antenna connection. Make sure the TNC connector is correctly threaded and tightened.
Step 2 If you are using a remote antenna, move the antenna cradle and check if the RSSI has improved.
Step 3 Contact your wireless service provider to verify that there is service availability in your area.
Retrieving the Electronic Serial Number
If your network provider requests the 11-digit decimal equivalent of your Electronic Serial Number
(ESN), you must retrieve your ESN, then convert it to decimal notation. See also, Converting
Hexadecimal ESN to Decimal Notation, page 25.
The ESN number is located directly on the modem label in hexadecimal notation. It can also be retrieved
using the Cisco IOS CLI using the show sprom module module number slot_number command.
The sample output below shows the ESN number:
Router (config-if)# show sprom module 5 1

lc-sprom linecard block header is invalid
cur_blk_hdr->block_length = 0067
