Unable to configure switch from telnet

leclair63 — Wed, 21 Oct 2020 20:28:21 GMT

I’m trying to telnet into a switch stack to configure a few ports, but when I do I get a completely different CLI than I’m used to. Its only for one stack as well, any other of my closets I want to connect to in PuTTY works just fine.

On the switches i’m trying to configure I get this prompt when I log in

telnet session telnet0 on /dev/ptyb0
login:

This doesn’t show up on any other switch I log into. How do I fix this so that I can configure switchports like normal?

Sorry if this is worded poorly or confusing, I’ve literally never encountered anything like this before.

leclair,

No that’s not what I’m asking about. I’m only stating that it shows up on the switch stack I’m unable to configure normally. I wasn’t sure if that was something that shows up when in a specific configuration or not so I added it to see if it helped

leclair,

I suggest to compare the output the show management on the two types of switches.

Here are the two switches, the top window is the type of CLI i’m used to working with, the bottom is the switches I’m trying to configure. I can’t go in on the bottom switch and do the standard >Enable >Configure Terminal >Interface Serial S0/0/0 like I can the top switch(Top and bottom regarding the windows in the picture)

Based on you getting the > instead of the # it looks like you are telnetting into a non-master. Is the IP address pointed at a MGMT port?

You can confirm this by using the “show stacking” command and see which slot is the master then telnet into that slot from the same interface “telnet slot <slot#>”

But I want the > and not the #. The window where I’m getting the # is the one I have no idea how it works. I just want to individually configure switch ports on that switch stack and I suddenly can’t or at least have no idea how.

This doesn’t sound like default EXOS. 🙂 The second screen is indeed default EXOS.

What exact model and Firmware is the switch in the first screenshot? I believe it is EXOS with Legacy-CLI, altough I’m not sure since I never used it. But this would also explain the “>” mentioned by Patrick Voss.

If this is the case, you have two options:

Execute the command “cli style extreme” on the first switch, then you have the default XOS CLI on both switches. But since you are not used to it…
Install the Legacy-CLI XMOD on the second switch (e.g. summitX-30.7.1.1.patch1-23-LegacyCLI.xmod; must match the currently installed firmware)

The switchports on a stack are configured from the master node. Can you help me understand what exactly you are trying to do? If you would like to configure ports on say slot 3 of a 4 node stack then you would log into the master, presumably slot 1 and configure slot 3 through there.

And actually re-reading your post I noticed you mention typing in enable and configure terminal. On EXOS there are no levels just one flat interface. Is this your only EXOS stack in your environment?

I don’t think that’s the problem. When he usually executes “>Enable >Configure Terminal >Interface Serial S0/0/0” then he isn’t using a normal EXOS, see my other posting.

Yeah we replied at similar times. I realize now that either this is his only switches running EXOS or he is used to the legacy CLI being there.

You hit it on the head. This is the only stack of switches in my entire network that aren’t running the legacy CLI.

So, rather than try and install any firmware I think its best that I figure out how to use EXOS.

What I’m trying to do right now is to go into one of the switches and then configure a single port’s IP address and tag a VLAN. How do I go about that? I’ve only ever known the old way.

Re: Unable to configure switch from telnet

Patrick_Voss — Thu, 22 Oct 2020 01:41:13 GMT

EXOS is very vlan centric. If you do not have the vlan created then you would use the command below:

create vlan <vlan name> tag <tag#>

From there you can add an ip address:

configure vlan <vlan name> ipaddress 10.10.10.1/24

And then add the port to the vlan as either tagged or untagged:

configure vlan <vlan name> add port 1 tagged

Great decision in my opinion!

create vlan VLAN-NAME tag 100
configure vlan VLAN-NAME ipaddress 10.1.1.1/24
configure vlan VLAN-NAME add ports 1 tagged

Please keep in mind that with a stack the port# will be in the following format:

<slot#>:<port#>
