Troubleshooting 

Unusual Network Activity 

This can also happen, for example, if the server is first configured to issue IP 
addresses with an unlimited duration, then is subsequently configured to issue 
IP addresses that will expire after a limited duration. One solution is to 
configure “reservations” in the DHCP server for specific IP addresses to be 
assigned to devices having specific MAC addresses. For more information, 
refer to the documentation for the DHCP server. 

One indication of a duplicate IP address in a DHCP network is this Event Log 
message: 

ip: Invalid ARP source: < 

IP-address 

> on <

IP-address > 

where:

 both instances of 

IP-address 

are the same address, indicating the 

IP address that has been duplicated somewhere on the network. 

The Switch Has Been Configured for DHCP/Bootp Operation, But Has 
Not Received a DHCP or Bootp Reply. 

When the switch is first config­

ured for DHCP/Bootp operation, or if it is rebooted with this configuration, it 
immediately begins sending request packets on the network. If the switch does 
not receive a reply to its DHCP/Bootp requests, it continues to periodically 
send request packets, but with decreasing frequency. Thus, if a DHCP or Bootp 
server is not available or accessible to the switch when DHCP/Bootp is first 
configured, the switch may not immediately receive the desired configuration. 
After verifying that the server has become accessible to the switch, reboot the 
switch to re-start the process. 

802.1Q Prioritization Problems 

Ports configured for non-default prioritization (level 1 - 7) are not 
performing the specified action.  

If the ports were placed in a trunk group 

after being configured for non-default prioritization, the priority setting was 
automatically reset to zero (the default). Ports in a trunk group operate only 
at the default priority setting. 

ACL Problems 

ACLs are properly configured and assigned to VLANs, but the switch 
is not using the ACLs to filter IP layer 3 packets. 

1.  The switch may be running with IP routing disabled. To ensure that IP 

routing is enabled, execute 

show running

 and look for the IP routing 

statement in the resulting listing. For example:
