But it does address one instance, where the ports can be in an "inactive" state. HTH Stefan *************************************************************************************************************** VTP Troubleshooting and Caveats Below are some common troubleshooting situations for VTP. How a Recently-Inserted Switch Can Cause Network Problems In situation, you have a large switched domain, which is all in the same VTP domain. You want to add one switch in the network. This switch was previously used in the lab and you enter the "good" VTP domain name. You configure it as a VTP client, and you connect it to the rest of the network. Then, you bring up the ISL link to the rest of the network. In just a few seconds, the whole network is down. What could have happened? The configuration revision of the switch you insert was higher than the configuration revision of the VTP domain. Therefore, your recently-introduced switch, with almost no configured VLANs, has erased all VLANs through the VTP domain. This will happen whether the switch is a VTP client or a VTP server. A VTP client can erase VLAN information on a VTP server. <bold><bigger>You will know that this has happened when many of the ports in your network go into inactive state, but continue to be assigned to a non-existing VLAN. </bigger></bold> Solution: Quickly reconfigure all of the VLANs on one of the VTP servers. *************************************************************************************************************** >I have a catalyst switch and a number of its ports are showing up as inactive. > >The cisco web page does not list inactive as one of the possible values in >the status field of a show port command, yet there it is > >Anyone know what this means????? >They were not connected until I assigned them to a VLAN, then they showed >up as inactive > >Thanks >Tom > >cat5000-3> (enable) sho port >Port Name Status Vlan Level Duplex Speed Type >----- ------------------ ---------- ---------- ------ ------ ----- >------------ > 1/1 notconnect 1 normal half 100 100BaseTX > 1/2 notconnect 1 normal half 100 100BaseTX > 2/1 inactive 4 normal auto auto >10/100BaseTX > 2/2 inactive 4 normal auto auto >10/100BaseTX > 2/3 inactive 4 normal auto auto >10/100BaseTX > 2/4 inactive 4 normal auto auto >10/100BaseTX > 2/5 inactive 4 normal auto auto >10/100BaseTX > 2/6 inactive 4 normal auto auto >10/100BaseTX > 2/7 inactive 4 normal auto auto >10/100BaseTX > 2/8 inactive 4 normal auto auto >10/100BaseTX > 2/9 inactive 4 normal auto auto >10/100BaseTX > 2/10 inactive 4 normal auto auto >10/100BaseTX > 2/11 inactive 4 normal auto auto >10/100BaseTX > 2/12 inactive 4 normal auto auto >10/100BaseTX > 3/1 inactive 331 normal auto auto >10/100BaseTX > 3/2 inactive 331 normal auto auto >10/100BaseTX > 3/3 inactive 331 normal auto auto >10/100BaseTX > 3/4 inactive 331 normal auto auto >10/100BaseTX > 3/5 inactive 332 normal auto auto >10/100BaseTX > 3/6 inactive 332 normal auto auto >10/100BaseTX > 3/7 inactive 332 normal auto auto >10/100BaseTX > 3/8 inactive 332 normal auto auto >10/100BaseTX > 3/9 inactive 333 normal auto auto >10/100BaseTX > 3/10 inactive 333 normal auto auto >10/100BaseTX > 3/11 inactive 333 normal auto auto >10/100BaseTX > 3/12 inactive 333 normal auto auto >10/100BaseTX > 3/13 inactive 334 normal auto auto >10/100BaseTX > 3/14 inactive 334 normal auto auto >10/100BaseTX > 3/15 inactive 334 normal auto auto >10/100BaseTX > 3/16 inactive 334 normal auto auto >10/100BaseTX > 3/17 inactive 335 normal auto auto >10/100BaseTX > 3/18 inactive 335 normal auto auto >10/100BaseTX > 3/19 inactive 335 normal auto auto >10/100BaseTX > 3/20 inactive 335 normal auto auto >10/100BaseTX > 3/21 inactive 336 normal auto auto >10/100BaseTX > 3/22 inactive 336 normal auto auto >10/100BaseTX > 3/23 inactive 336 normal auto auto >10/100BaseTX > 3/24 inactive 336 normal auto auto >10/100BaseTX > 4/1 notconnect 1 normal auto auto >10/100BaseTX > 4/2 notconnect 1 normal auto auto >10/100BaseTX > 4/3 notconnect 1 normal auto auto >10/100BaseTX > 4/4 notconnect 1 normal auto auto >10/100BaseTX > >Tom Pruneau >Trainer Network Operations > >GENUITY >3 Van de Graff Drive Burlington Ma. 01803 >24 Hr.
