How do I make a Cisco port act like a dumb switch?

[jmr_snolab]

Hi Folks

I have an old telnet power switch.  When I connect it directly to a Cisco Catalyst C2960X, I cannot ping it.  When I put an unmanaged (dumb) switch in between, I can ping it.  I tried a cross-over cable, but that did not help.  I tried adding the extra config statements, beyond the vlan 52 lines, one at a time to no avail. Here is the config:

 switchport access vlan 52
 switchport mode access
 switchport nonegotiate
 power inline never
 speed 10
 duplex half
 no mdix auto
 spanning-tree portfast

How do I make a Cisco port act like a dumb switch?

Can you define what you mean by a "telnet power switch"?

Also, when you connect it directly to the C2960X, what is the interface status on the Cisco?

[jmr_snolab]

It is a WTI TPS-2 network power switch.  We can telnet or ssh into the box to control the power of other devices.  Those devices can be rebooted, powered off, or powered on remotely.  After a power outage, there are settings that permit it to have a delayed start.  From their website:

"Electronic equipment sometimes 'locks-up', requiring a service call just to flip the power switch to do a simple reboot. The TPS-2 Telnet Power Switch gives you the ability to perform this function from anywhere on the LAN/WAN..."

The status is up when connected to the Cisco directly.  The logs did not provide any information either sadly.

Just checking, you tried connecting without all those other configs?

Only -

 switchport access vlan 52
 switchport mode access
 spanning-tree portfast

If so, maybe try changing the the auto negotiation to allow only 10Mb

speed auto 10

duplex auto full (or half if you think that may work.)
