Packet over SONET failback
by Jason Lixfeld 14 Feb '11

14 Feb '11

PoS failure detection happens in under 50ms, but what about the failback? Same deal? I ask because I've got two routers connected to opposite ends of a spare PoS link that I've been playing with and I'm noticing that the failback on the far side seems to be about 15 seconds (assuming the near side failover was initiated with an interface shutdown command and thusly no shut'd to re-enable the link). Just wanted to know if a higher failback time is a relatively normal occurrence and maybe I'm seeing some sort of built-in hold down feature working away?

Putting foil (yes i try almost everything) near LNB doesn't affect interference level too.

Combining 10g tap ports
by Eric Gauthier 13 Feb '11

13 Feb '11

Hello, I'm wondering what are people's experience is with boxes, like those from Gigamon, to aggregate 10g span ports? Any recommendations? As background, we currently have a sensor network where we provide our InfoSec team with taps from various points in our network. In cases where we have redundant routers, we've taken a tap from each one, fed it into a switch, then span'ed the two ports into a third so that we can present them with a single feed for each location because, according to them, they can not re-assemble data from different interfaces on their sensors. We have an "opportunity" to revisit this design now that we're moving to 10g router interlinks. Eric :)

It does make it easier to > change who performs root service operation (hence the politics). Exactly: it *centralizes control* over what the roots are. The second- and third-order resultants of that observation will be left as an exercise for the student; politics are off-topic for NANOG :-) Cheers, -- jra

Old Annex question
by Brian Feeny 13 Feb '11

13 Feb '11

Sad but true, I still have a few of these in operation as terminal servers. In reading the documentation I could find it wasn't clear to me how to solve my issue. I use these to manage Cisco routers. How can I connect to a server, and then drop back to the CLI, so I can then connect to another server, and keep switching back and forth? I thought I could just set the attn_string to say "^A" and then I could just hit that and it would work, but it doesn't seem to. I basically want to emulate the same functionality you can get when you do ^^x on a Cisco terminal server (2509/2511/etc). here is how its configured right now: %rotary host1: 1(a)172.16.1.10 host2: 2(a)172.16.1.10 host3: 3(a)172.16.1.10 %gateway annex 172.16.1.10 net default gateway 172.16.1.1 metric 1 hardwired end So I connect to my annex by telnetting to 172.16.1.10, then I type say host1, but I want to drop back to the CLI, any ideas how to escape to CLI once connected? I figured that since many of you are from my same era and these were popular with ISP's of the day, someone here may know...... Brian

Internet blocked in Algeria?
by Joly MacFie 13 Feb '11

13 Feb '11

Any confirmation of internet blocking? http://bikyamasr.com/wordpress/?p=26849 As massive street demonstrations are met with widespread violence in Algeria, the country is reporting that many Facebook accounts have been deleted or blocked by the government, in an effort to stifle protests against President Abdelaziz Boutifleka, activists on Twitter reported around midday in the country. They also said that the government is working fast to cut off all Internet providers in the country. -- --------------------------------------------------------------- Joly MacFie 218 565 9365 Skype:punkcast WWWhatsup NYC - http://wwwhatsup.com http://pinstand.com - http://punkcast.com VP (Admin) - ISOC-NY - http://isoc-ny.org ---------------------------------------------------------------
