Hello,
Is there a summary command to show whether the ports on a switch are in half or full duplex and in 10/100/1000?
Thanks

Hi
And you can also use the mode button on the switch.
That will most of the time tell you the information also.
Good luck

show controller if available. if not check show log
sw4#show contr g0/3 | i ull
Device status = full-duplex, link upshowing output from only relevant section
sw4#show controllers g0/3
..
Register decodes:
Status : 0x80080783, FD, UP, 1000Mbps, Auto1000Mbps, PCI
Control register : 0x00000040, HD, SetLinkUP, 10Mbs
Control register ext: 0x00000000, CopperRxdescriptor addr=09594E00 len=00000000, stat=00000000
Txdescriptor addr=06CC5B87 cmd/len=0B00003C, stat=00000001
RX is enabled, TX is enabled
Device status = full-duplex, link up
PCI width = 32, PCI66=0, PCIX=0, PCIXSPD is 50-66MHz Device Speed = 1000Mbps...
show interface status just says auto which is uselsss...

Hi all,
Nice answers. Another way to find out whether the ports on a switch are in half or full duplex is using CDP with the command show cdp neighbors detail
Please find below the output. It shows the neighbor duplex operation.
SW-L3-02#show cdp nei det
-------------------------
<output omitted>
Native VLAN: 1
Duplex: full //shows the neighbor duplex operation.
Management address(es):
IP address: 192.168.1.10
Hope it helps.
Kind regards,
