Avaya has released an updated version of it’s Ethernet Routing Switch 8600 Planning and Engineering Network Design document. The document, NN46205-200, Rev 02.02, was originally released with the 5.1 software release for the Ethernet Routing Switch 8600. The document has been updated to include some of the features and changes incorporated into the software since the document was originally published.

There’s a lot of great technical information in this document including a lot of recommendations and best practices.

Cheers!

When is enough tech really enough?

I was greeted with this little gem tonight and couldn’t resist the urge to fire up Paint and make my mark… it reminded me of an article that was posted on the New York Times recently titled, Digital Devices Deprive Brain of Needed Downtime. As of late I would say that I agree with the Matt and the researchers at University of Michigan. I generally try to make sure I balance my life with work and play, with physical activities such as working out or playing ice hockey and with spending time with the family and my growing daughters. I’ve thankfully avoided the crack-berry syndrome and I have intentionally not configured my Droid to use ActiveSync with my work Exchange Server, just using POP3 to get my personal email thank you. There’s no technology pervasiveness around us, just look around yourself. It’s in your home, in your car, at your place of work, and you probably carry a fair bit of it around with you daily.

I’m curious how other IT professionals feel about the subject? Is it just fodder or do you feel it’s visibly impacting your life?

Personally I feel it’s just like anything else in life, too much of a good thing ain’t a good thing.

Cheers!

Cisco Nexus Switch Backups with Perl SNMP

Sep 1st

I’ve spent some time over the past few days trying to get our home grown Perl script designed to backup all our network switches to work with the Cisco Nexus 7010 and 5010 switches.

With previous Cisco switches such as the 6509, 3750, 2960, etc we know that the following commands (when sent via a Perl script using the Net-SNMP Perl module) would instruct the switch to copy it’s running-config to a TFTP server.

snmpset -v1 -c$COMMUNITY $HOST ccCopyProtocol.$RANDOM i 1
snmpset -v1 -c$COMMUNITY $HOST ccCopySourceFileType.$RANDOM i 4
snmpset -v1 -c$COMMUNITY $HOST ccCopyDestFileType.$RANDOM i 1
snmpset -v1 -c$COMMUNITY $HOST ccCopyServerAddress.$RANDOM a "10.1.1.50"
snmpset -v1 -c$COMMUNITY $HOST ccCopyFileName.$RANDOM s "sw-train-acme.cfg"
snmpset -v1 -c$COMMUNITY $HOST ccCopyEntryRowStatus.$RANDOM i 1
sleep 5
snmpget -v1 -c$COMMUNITY $HOST ccCopyState.$RANDOM
#if not successful sleep 3 and re-check ccCopyState else continue and destroy table entry
snmpset -v1 -c$COMMUNITY $HOST ccCopyEntryRowStatus.$RANDOM i 6

I know that the both the Cisco Nexus 7010 and 5010 both balk at the SNMP OIDS/MIBS used above. So I’m searching for a set of equivalent SNMP OIDS/MIBS as those in CISCO-CONFIG-COPY-MIB for NX-OS. I’m not sure that such a OID/MIB even exists for NX-OS but it doesn’t hurt to search and ask.

I’m curious if anyone else has come across this issue? I know that there is an XML interface available but I would prefer to keep using the PERL/SNMP script that I’ve already developed. In the interim I’ll probably write an Expect script (or add some Expect code to my existing Perl script) to remotely connect to the switches and issue the appropriate copy commands.

Cheers!

Avaya has re-released two technical configuration guides the detail configuring the Communication Server 1000 5.0 for SIP trunking with Telecom Italia and BT Italy. I also took the time to go back and search for any previous guides that I might have missed and here’s what I found;

I’ve been very busy as of late with work and hope to write some original posts very soon.

Cheers!
