No point in leaving this question open forever. &nbsp;I am planning to update the IOS on all my switches sometime soon. &nbsp;Hopefully this will take care of the problem. &nbsp;Thanks for your help.

Heya Fellow &quot;Experten&quot;,<br />
<br />
&nbsp;We have a LAN utilizing Cisco switches. We have a mix of 2950's, 3500XLs, and 2900XL switches. The issue is VTP. When trying to configure a VTP password, we get an MD5 mismatch on 2 switches: The WS-2950G-48-EI models running IOS 12.1(19)EA1c and 12.1.(14)EA1a come up with a completely different MD5 hash for the password. All other switches have the same MD5, only the two 2950's running those particular IOS come up different. Note those two come up with the same hash, but its different from all the others. All the usual things have been checked, such as inadvertent spaces etc. &quot;Sh VTP Pass&quot; reveals the passwords are EXACTLY the same...yet the MD5 hash is different. We have googled this until our eyes popped out to no avail. Can anyone shed any light on this situation?<br />
<br />
We have a 2950T-24 running IOS 12.1(22)EA5 and I am tempted to just copy that IOS over to the two problematic switches. Any reason that wouldn't work?<br />
<br />
Regards,<br />

VTP MD5 hash issues betwwen IOS version

A switch is a device that filters and forwards packets of data between LAN segments. Switches operate at the data link layer or the network layer of the Open Systems Interconnection (OSI) Reference Model and therefore support any packet protocol. LANs that use switches to join segments are called switched LANs or, in the case of Ethernet networks, switched Ethernet LANs. A hub is a connection point for devices in a network. Hubs are commonly used to connect segments of a LAN. A hub contains multiple ports; when a packet arrives at one port, it is copied to the other ports so that all segments of the LAN can see all packets.
