I think you should do "clear/phy/show" in this order.Is there a way to find out fiber cable length on either a 6450 or 7250? I am thinking about buying a premade 6 strand OM5 LC/LC to replace my OM3 cable - for no other reason than 'because' - only thing is i am not sure what size fiber cable I have now & it is the same route for the new one.
I tried :

Sorry if it's been already answered somewhere, tried to do some googling first, but still not clear. I've just won an auction for a couple of ICX 6610, and only after proceeding to the checkout, re-read the description again - and realized I somehow missed this:
"DEVICE IS FULLY WIPED AND WILL NEED REIMAGED/SOFTWARE,SET UP AND CONFIGURED!! DEVICE DOES TURN ON AND WAS WIPED!
"SWITCH CONTAINS NO BOOT IMAGE! A NEW BOOT IMAGE WILL NEED TO BE UPLOADED BEFORE CONFIGURATION!"
I've read the guides from the first post, but they seem to be about firmware upgrading, configuration etc, I couldn't find anything related to fully wiped switches with no boot image. Is this going to be a problem, or I'll be able to just upload new images / firmware by myself?
Also, while waiting for your 6610s, go grab a console cable, if you don't already have one. You'll need it.You will be fine, just follow the guide. It will likely power on directly to the bootloader prompt. Make sure to read the update guide carefully, and prepare for the steps in advance. Your 6610 will be in full howl mode until you get the OS booting, so it's in your best interest to move through the steps as quickly as possible.
Thanks, I don't have a console cable yet. I'm looking at the pictures of those 6610-48p switches, and can't see any weird ports on them (like usb, serial etc), does it mean that I'm gonna be plugging the console cable into one of those rj45 ports in the back? So the console cable is going to be rj45<=>rj45 then? Can't I just make one by myself then, with a crimp tool?Also, while waiting for your 6610s, go grab a console cable, if you don't already have one. You'll need it.
That's right. You'll be plugging the cable onto the RJ45 port on the right (closest to the 40Gbps ports, the one with the ones-and-zeroes label under it). Those console cables are going USB <-> RJ45. The USB portion has a USB-to-serial chip embedded in them with the correct wiring going to the RJ45 end.Thanks, I don't have a console cable yet.

TDR / cable phy is only for native copper portsI did the clear:
Then I went out of conf tCode:SSH@ICX7250-48P Router(config)#clear cable-diagnostics tdr 1/2/1
I tried it with 1/2/8 (not part of a lag)Code:SSH@ICX7250-48P Router#phy cable-diagnostics tdr 1/2/1 This feature is only supported when the interface is configured for Auto-Negotiation
I might be close?Code:SSH@ICX7250-48P Router#phy cable-diagnostics tdr 1/2/8 This feature is only supported when the interface is configured for Auto-Negotiation
1/2/1 is part of a lag, 1/2/8 is plugged into a unifi 1gb optic so its slowed to 1gb
next I turned off a part of my lag:
lag uplink
disable e 1/2/2
long story short, disabled a port from each lag, tried again, still didnt work.
Any other ideas?
Wait, do I need a "usb<=>rj45" console cable, or an "rj45<=>rj45" console cable? It's just from reading the fohdeesha's update guides I've got the impression that one end of the cable goes into the switch (and that's rj45, at least in case of icx6610), and the other end is connected to my network (so also rj45):You'll be plugging the cable onto the RJ45 port on the right (closest to the 40Gbps ports, the one with the ones-and-zeroes label under it).

So I thought I'll just need to assemble the wires in some specific order and crimp a regular cat5 cable. Google found me this, which suggested it's as simple as swapping some pins and then crimping as usual:Fohdeesha Docs said:Connect to the switches serial/console port using a program like Putty (9600 8N1), and connect the dedicated management port to your network (do not use a "normal" port).
Sorry for the confusion. I hadn't noticed that RJ45 <-> RJ45 cable was part of that list.Wait, do I need a "usb<=>rj45" console cable, or an "rj45<=>rj45" console cable?

What is the name of the cable (RJ45 to RJ45) that can be used to connect from a KVM to Cisco serial port?
As everybody knows Cisco's console ports are RJ45. However, the cable they come bundled with is DB9 to RJ45. We have a KVM that allows managing network devices via a serial port but the port on the...serverfault.com
That amazon link in your post lists all kinds of cables, there are rj45<=>rj45 there, rj45<=>usb, rj45<=>db9, so that got me confused.Do I need an rj45<=>rj45 serial cable, like this one? https://www.amazon.com/Cisco-Console-Rollover-Cable-RJ45/dp/B004Z9YG5W/
I don't see any chips embedded in the pictures.
Lol, I'll probably have a hard time learning these switches if I'm so dumb that I can't even figure out the serial cable thing.![]()
Oh, that's lovely, I might have to get one of those; I currently carry around a regular USB to DB9 dongle and my Cisco cable. I do have some switches that use different pin outs though, so have DB( as the common element is handy.Sorry for the confusion. I hadn't noticed that RJ45 <-> RJ45 cable was part of that list.
Here's an example of the cable you'll need (that's the one I have):
AmazonSmile: OIKWAN Console Cable,USB Console Cable, USB to RJ45 Console Cable with FTDI chip Compatible with Cisco, Huawei,HP,Arista,Opengear,Aruba,Juniper Routers/Switches for Laptops in Windows, Mac, Linux: Computers & Accessories
It's an USB <-> RJ45 cable. It has an embedded USB-to-serial chip on the USB side of the cable and it has the correct pinout on the RJ45 side. There exist many ways to connect to equipment over serial, but this is the one that will work with the 6610s.
Hey @jht3 I am interesting in testing out VyOS on the edge as a firewall with a transit vlan and my 6450 L3 switch hosting multiple Internal vlans. I've not found any howtoo's specifically for setting this up in the VyOS cli. Do you know of any or have some basic tips beyond the nat masquerade rule here?@itronin
i guess i didn't think it was relevant? my fw is Vyos.
and you are spot on. no, i don't have a NAT rule for 172, only 10.0.0.0/16.
added the nat rule and problem solved!
Code:vyos@vyos# show nat source { rule 1 { outbound-interface eth0 source { address 10.0.0.0/16 } translation { address masquerade } } rule 2 { outbound-interface eth0 source { address 172.16.0.0/30 } translation { address masquerade } } }
If your main concern is fitting it down an existing conduit, I'd go with MPT/MPO terminated cables, and get fanouts that plug into them, rather than trying to stuff the full 12xLC fanout down the conduit.So the question is:
1. Any thoughts on a pretermintated 12 strand LC to LC?
2. As I am buying a new cable, should i consider other formats? SC, singlemode, etc?
There are some other differences too: the 7250 runs newer FW, is linux-based instead of a custom OS, possibly more compatible with newer brocade/ruckus gear, and probably most importantly for Ebay, the licensing is honor-based rather than enforced, so people who are not on this forum can use all the 10g ports without having to track down and pay for an additional license.Why is 7250-48P so much more desirable than 6610-48P?
I'm trying to score a 7250-48P to run as the core switch from my home but I'm encountering ridiculous prices even using offers. Meanwhile, there are loads of (relatively) cheap 6610's available. It's kind of hard to believe a multi-hundred dollar difference is down to power usage and noise. Is there some other advantage I'm missing?
Wondering if I should buy a 6610 instead and save $$$...
