The few Arista switches I have worked on seemed alright to me. The CLI is an awful lot like IOS. We don't have many customers on them so I don't run across them very often though.

We're doing a switching refresh and Arista has been really aggressively courting our network guy for the business. Their main selling point is "WE HAVE SUB PICO SECOND LATENCY! PACKETS LITERALLY TELEPORT DIRECLTY BETWEEN HOSTS!" Which is cool but I don't run a high frequency trading operation and just don't have that kind of requirement in my environment. We're primarily interested in cost, with ease of management and automation support a close second. By those metrics, we ended up going with a bunch of Juniper QFX stuff. Also I assume that was a tongue in cheek comment on the similarity between Cisco IOS and Arista, but yeah.

Well, they quoted the guy that I'm working with for like 1/3 of the cost of Cisco. With that being said, Cisco overengineered the gently caress out of the solution they quoted them on, so I may have been able to talk them back over to Cisco on the grounds that ISE will resolve several major problems they have AND they won't have to run a 6800s in VSS at their core.

By default, EIGRP load-shares over equal-cost paths. So yeah, you probably have some load balancing going on there. Fine for your core or aggregation layer. Not so useful for the access layer where you probably have stateful firewalls which will rightly block asymmetric TCP traffic.

sh ip cef 0.0.0.0/0 will give you insight into the actual hashing. Although it looks like both next hops are on the same L2 segment via the same interface.

Are there any substantial difference between the 642-902 (CCNP Route) exam and the new 300-101 (Routing V2) exam? From what I understand, the 300 exam has replaced the 642 for the CCNP. I'm supposed to take the 300 exam in a few months, but I just realized Odom's book that I have been using is for the 642 exam. Edit: New exam is 300-101, not -001.

Yeah, I'm mostly looking for ospfv3 functionality so that I can have a fully meshed core with ipv6 dual stack. Brocade went back to a commercial implementation of zebos, whereas Quagga's project page still says quote:Support for OSPFv3 and IS-IS is various beta states currently; IS-IS for IPv4 is believed to be usable while OSPFv3 and IS-IS for IPv6 have known issues. welp. I've got 1-2 Brocade Vyatta routers in production, and a few more VyOS as well, with a few hundred Edgerouters at customer sites, and with ARIN's IPv4 delegations running out by the end of this year, the urge to get customers on board with IPv6 would be a year-end dream goal for me.

Looking for a bit of help from dudes that know a lot more than I do. I'm working wth 2 (well currently 1, because the second one bricked on me) AIR-CAP1532I-A-K9 devices, supposedly they should pull an address from DHCP out of the box instead of being static, which is completely false. I've never once configured cisco gear and I'm trying to blunder my way through this. How can I configure this thing to pull an address from DHCP? It's currently statically assigned 10.0.0.1, but I can't access the web interface, perhaps HTTP/HTTPS is turned off natively or something. I've got console access for the one that isn't broken (the bricked one is not showing anything on the console connection even during reboot, so I'm guessing the flash memory got wiped) but I'm apparently an idiot and don't know how to google for what I'm trying to do. So either A) I need to figure out how to turn on http/https so I can access the web GUI, or B) I need to just figure out how to configure it to pull an address from my DHCP server via the CLI. This was supposed to be easy, configure option 43 on my server and voila, it talks to our WLC and we're good to go, but of course nothing is that easy

This isn't actually Cisco but maybe some of you have worked on them before...I'm configuring AdTran 3430's for the back office of some retail locations. The people working at the locations aren't always the most technically inclined, and sometimes they plug things into places they shouldn't when they think things are broken. I'd like to configure DHCP snooping so that our firewall doesn't pull a DHCP address from another device plugged into the switch, but I can't see find a way to do it. Anyone happen to have used AOS before? I could just remove unused ports from the main VLAN I suppose, but I'd prefer something more plug-n-play.

I'm not sure if AOS has a IOS DHCP snooping equivalent but maybe you can accomplish what you're trying to do with an access-list? Allow DHCP traffic on the port you're expecting your DHCP server requests/responses to come from and deny it everywhere else.

What do you guys do if you need more ports at a location where you might not be able to or want to pay an electrician to run more drops to? I need a small and inexpensive managed switch that has 802.3af, 802.1x, STP, CDP/LLDP and preferably a CLI. Is an 8 port 2960 my best option?

I've got to agree with the love for the C series, especially the 3560Cs. My favourite is the CPD switches - these can be powered via PoE from uplink switches and a couple of those models can even pass through that power to other devices!

Verify this by plugging a console cable, restarting the AP and getting the image name as it loads it, it'll be something like "c1530-k9w7-morestuff.tar". If it k9w7, its autonomous/standalone, if its k9w8, its lightweight. I've only used 3600 series AP's but from what you're describing, it sounds like its got an autonomous image on and not a lightweight image, so it won't go and boot from your WLC. When my 3600's boot, if they dont get an IP they will just sit there with no IP address all day. Or maybe its just a difference between the 1500's and the 3600's If it is on lightweight, then have a read about the boot process and how it will try to boot, it might help you figure out why its not getting there: http://www.cisco.com/c/en/us/td/docs/wireless/controller/7-0MR1/configuration/guide/wlc_cg70MR1/cg_lwap.html#pgfId-1459171 Ahdinko fucked around with this message at 11:17 on Apr 30, 2015 |

So I've got two 3750E's in a simple stack, and we're having a problem where we get a crash, then a stack re-election and the stack master changes. I'm not sure if the stack master election is a symptom or a trigger for the crash at this point. My question is, if there is a hardware failure issue, what are my options for determining which switch in the stack is having trouble? From the logs we have, it appears that the stack is treated as a single unit.
