Go to SolutionSpanning-tree question
I have a core of stack of 4 PowerConnect 7048 switches. There are some unacceptable delays on the network so I am cleaning up configurations and checking spanning-tree as these were configured by he previous admin. On the four active 10 GB links, the spanning-tree reports different states:
two are
Port Te3/2/1 Enabled
State: Disabled Role: Disabled
Port id: 128.167 Port Cost: 0
Port Fast: No Root Protection: No
Designated bridge Priority: 4096 Address: 5C26.0AAA.1EA6
Designated port id: 0.0 Designated path cost: 0
CST Regional Root: 80:00:5C:26:0A:AA:1E:A6 CST Port Cost: 0
Root Guard..................................... FALSE
Loop Guard..................................... FALSE
TCN Guard...................................... FALSE
Auto Portfast.................................. TRUE
and two are
Port Te2/2/2 Enabled
State: Forwarding Role: Designated
Port id: 128.112 Port Cost: 2000
Port Fast: No Root Protection: No
Designated bridge Priority: 4096 Address: 5C26.0AAA.1EA6
Designated port id: 128.112 Designated path cost: 0
CST Regional Root: 10:00:5C:26:0A:AA:1E:A6 CST Port Cost: 0
Root Guard..................................... FALSE
Loop Guard..................................... FALSE
TCN Guard...................................... FALSE
Auto Portfast.................................. TRUE
.I would think the first indicates an issue and all should report as Forwarding and Designated. Is this correct and if so, how can this be done?
Thanks

Hi,
A disabled state is not being used. If you do no spanning-tree disable it should enable it. http://downloads.dell.com/Manuals/all-products/esuprt_ser_stor_net/esuprt_networking/esuprt_net_fxd_prt_swtchs/powerconnect-7024_Reference%20Guide_en-us.pdf page 745
