No problem. I have a longer version, and some other stuff, on GitHub if you're interested.

Re: Beginning Network Automation (SDN) - Python in GNS3

I haven't done anything with it yet. I just got my hands on the EFT APIC-EM release so I've been tinkering with its API for the past couple days. I need some lab devices that support OnePK soon.

Re: Beginning Network Automation (SDN) - Python in GNS3

I'm not sure why people use pexpect so much. I just run Paramiko and pause for a second. It looks a lot cleaner to me and you should know what's coming on the line after your command anyway. import paramiko import time device = "1.1.1.1" conn_pre = paramiko.SSHClient() conn_pre.set_missing...

Re: Nexus Setup

Yeah, I think you're right that it's not overly complex. I just think adding any complexity or extra cost, for little quantifiable gain, can be a tough sell. Just for the record, I'm not saying that I would never deploy a true OOB management network. I'm just saying it's very rare to see in real lif...

Re: Nexus Setup

That's what the extra internet uplink is being considered for: a device with static IP to VPN into directly in the OOB (using local usernames of course, no production Radius). That would introduce a backdoor though so it's something to be careful for. And sure, you can console in, but being able to...

Re: Nexus Setup

@ Vito: we have a completely separated OOB network here. And it pays off for sure. - Layer 2 campus switches. Considering you don't need these OOB ports on the main Nexus infrastructure, it's not that expensive. For once even LAN Lite image without QoS is an option. - One/A few VLANs for OOB - For ...

Re: Nexus Setup

A truly dedicated OOB should not touch the core infrastructure at all and should be built on separated infrastructure. I think most good Colo would have separated OOB infrastructure that you can build off on for the OOB network. This will come in handy the day/night a network change goes wrong and ...

Re: Nexus Setup

With that being said, it is definitely much better to make use of the management port and to have a dedicated OOB access to your core switch. Why? If the core is down the OOB network is likely down too, unless OOB doesn't pass through the core at all, and you have completely separate infrastructure.

Re: Nexus Setup

You can have an SVI up for management. It's just like a Catalyst switch. The only reason (that I've ever seen) to use the dedicated management ports for management is DCNM. I'm not sure if it's changed, but a couple years ago you were only able to manage a device in DCNM using the management ports....

Re: Cisco ACI

Ugh... why do you just insist on trolling this out Vito. This is getting into a semantics flame war at this point with no real value to anyone. A one-sided flame war at that. You think I'm trolling you? I'll fully admit that I've gotten snarky as the thread progresses, but I think it's warranted co...

Re: Cisco ACI

Sorry, I pasted the wrong thing that you didn't address, it was supposed to be this: Partner integration is an interesting one. I think it's a completely different scenario when you look at Cisco vs Arista partnerships. Arista does one thing while Cisco does countless things. I'm shocked they're par...

Re: Cisco ACI

Glad you didn't run away. Merchant silicon is a good thing because the vendor doesn't have to have expensive dedicated staff and facilities in order to fabricate and program it. This means generally getting things to market much faster than competitors using custom silicon. It also breeds competitio...

Re: Cisco ACI

You'll have to email the new admins. Mods can't do it, and Steve didn't like the idea. The new guys might feel differently. You always have the option to stop visiting the site. That doesn't require an account deletion.

Ps. Your reaction to all of this is very mature.

Re: Cisco ACI

So that's your take on all of this? Yet again, instead of addressing others' points, you deflect, point fingers, and plan to walk away? Should we expect another nitpick in a couple days?

Re: Cisco ACI

Sorry to re-hash this, but this is not only a response to you and also to burnyd's question regarding if Arista has a TRILL product. I'm watching BRKDCT-3640 and I think one of Cisco's Principal Engineers put it best (at around 1:20) that Cisco will support FP for years, but the industry has transi...

Re: Cisco ACI

I don't think ACI is going to take over the world and I'm happy to stick with FP for now. I think you'll see ACI take over in BIG data centers, companies that are in the DOW/S&P, but for everyone else - it'll be a FP/vPC. Yeah, that's kind of what I'm assuming as well. I really need to see all ...
