| Description | Unable to open SNMP channel (UDP port port) on interface interface_number, error code = code |
| Explanation | "This is an SNMP message. This message reports that the Cisco ASA is unable to receive SNMP requests destined for the Cisco ASA from SNMP management stations located on this interface. This does not affect the SNMP traffic passing through the Cisco ASA through any interface. An error code of -1 indicates that the Cisco ASA could not open the SNMP transport for the interface. This can occur when the user attempts to change the port on which SNMP accepts queries to one that is already in use by another feature. In this case, the port used by SNMP will be reset to the default port for incoming SNMP queries (UDP/161). An error code of -2 indicates that the Cisco ASA could not bind the SNMP transport for the interface." |
| User Action | After the Cisco ASA reclaims some of its resources when traffic is lighter, reenter the snmp-server host command for that interface. |
