In my network, I have a main Cisco 2950 that connects to my outside bandwidth, then individual Cisco 2950s in each cabinet that connect back to the main one.
I recently had someone in one cabinet start consuming 100% of the bandwidth in my network. As a quick fix, I set the speed on the main switch to be 10Mbps for the port that connects to the switch in the cabinet.
After doing that however, the port now shows down (notconnect). I've tried setting the speed back to 100, and shutting down/starting the port again, but it never reconnects. Any recommendations on getting this port back up, short of rebooting the switch in the end cabinet (I can't connect to the switch)
Here is what I did:
config t int FastEthernet1/0/47 speed 100 duplex full end
Even after resetting the speed, I'm getting:
sh int FastEthernet1/0/47 FastEthernet1/0/47 is down, line protocol is down (notconnect) Hardware is Fast Ethernet, address is 0016.4797.4633 (bia 0016.4797.4633) MTU 1500 bytes, BW 10000 Kbit, DLY 1000 usec, reliability 255/255, txload 1/255, rxload 73/255 Encapsulation ARPA, loopback not set Keepalive set (10 sec) Full-duplex, 100Mb/s, media type is 10/100BaseTX
Before changing the speed:
sh int FastEthernet1/0/47 FastEthernet1/0/47 is up, line protocol is up (connected) Hardware is Fast Ethernet, address is 0016.4797.4633 (bia 0016.4797.4633) MTU 1500 bytes, BW 100000 Kbit, DLY 100 usec, reliability 255/255, txload 1/255, rxload 209/255 Encapsulation ARPA, loopback not set Keepalive set (10 sec) Full-duplex, 100Mb/s, media type is 10/100BaseTX
