So any prizes for having the oldest boot image? Just got mine up and running ver. 1.0.0.10. Has anyone figured out or looked into what the differences are between versions? If someone is interested in it here is the link to what I have pulled together and mine. LB6M
Code:
(FASTPATH Routing) #show bootvar

Pardon my ignorance but why is SSH preferred over telnet?

Telnet is plain text / not secure while SSH is encrypted.

SSH aka "Secure Shell" :)

For my purposes, security is a non issue so would I gain anything functionality wise by switching to SSH?

OK, you talked me into it. It's on my todo list for tomorrow. :)

show me the config for the ports in question: do a show run, and then hit <space> at the --More-- or (q)uit

Also...if you connect the 2 Windows machines together with a DAC, can you ping?

HMMMMMMMM. Looks like you're not showing any interfaces at all. Which is VERY odd, since you said you can see traffic passing between some interfaces.

ok let start with a

show interface 0/1

see anything?

My server sees the internet, my workstation pc sees the internet, my personal pc sees the internet, all are connected through DAC cables to ports 24, 23 and 22, but it seems like the 10gb ports are not talking to each other?
(FASTPATH Routing) #show port all

...
0/22 Enable 10G Full 10G Full Up Enable Enable long
0/23 Enable 10G Full Down Enable Enable long
0/24 Enable 10G Full Down Enable Enable long
0/25 Enable Auto 1000 Full Up Enable Enable long
0/26 Enable Auto 1000 Full Up Enable Enable long
0/27 Enable Auto 1000 Full Up Enable Enable long
0/28 Enable Auto 1000 Full Up Enable Enable long
Ports 23 and 24 are Down. So whatever is plugged into them is not talking to the switch.

What is plugged into 26 - 28?

Does "show port all" show the ports up or down? May be a bad DAC, wrong kind of DAC (is it passive or active), too long a DAC, etc. Validate all the cables with the known working device. If they are good, what are the other differences? What make cards? Try different ports on the switch, 23 and 24 may be bad. One at a time, use port 22 with your other devices and see if they come up.

Okay, Layer 1 looks ok. Do "show interface 0/23" and "show interface 0/24" and post the output to verify Layer 1.

Then do "show mac-addr-table" and post the output to verify Layer 2. Make sure they match the devices MAC addresses.

If you are not using the routing features do a "no ip router" to simplify troubleshooting.

See if you can ping each device from the switch.

Finally i tried the no ip router command. it seems like the "no ip router" command is invalid, or not working on the lb6m.
Woops, I meant "no ip routing". You have L3 active on the switch. That should disable it.

Since you have MACs on the switch. Layer 2 seems to be ok. And there is traffic on the ports.

On the PC/Server try to ping the other and see if the ARP table shows the correct MAC to IP mapping.

I'm having an issue with vlan configurations.

I have a router tagging vlans 5,10,15,20,25,30,35. I linked the switch to my router on port 27 and included all of those vlans in the participation with a pvid of 1.

I then went to configure port 26 and included vlan participation on vlan 5 and set the pvid to 5. When I go to plug in something to port 26, I don't get an IP from my router.

Can you guys help me figure out what I'm doing wrong?

Thanks!

What you did is exactly right. I'll ask the obvious first:

1. Are you actually running a DHCP server on that VLAN?
2. If you set a static, can you ping anything on vlan 5?

@derekvw91: Post your configs.

I assume that your router is running DHCP on that segment and VLAN interface.

Post the output of: "show vlan", "show vlan 5", "show vlan port all"

As with #2 from @dwright1542: give the device a static IP in that subnet and see if you can ping the ip address of VLAN 5. That will tell us if the VLAN setup is correct.

Default does not support JumboFrames. Simple to configure across the whole switch:

enable
configure
interface 0/1-0/28
mtu 9216
exit
copy system:running-config nvram:startup-config
exit
logout
