Russian locale for Cisco 7821 IP Phone

While configuring Russian locale on CME, I came across a problem where 7821 phones would not switch to Russian locale. Turns out these phones look for localization file with different alias than the one created by CME router when locale is loaded and extracted.
Default alias looks like this:

tftp-server flash:its/russia_sp-sip.jar alias SIP_Russian_Russia/sp-sip.jar

We need to add an additional alias like this:

tftp-server flash:its/russia_sp-sip.jar alias SIP_Russian_Russian_Federation/sp-sip.jar

Virtual Chassis configuration on Juniper EX4600

So yesterday I’ve been configuring a two-member Virtual Chassis on Juniper EX4600. I’ve been following the guide but configuration wouldn’t save when issuing commit or commit synchronize command with the following error

Member’s information missing from provisioning database

Turns out, when adding members to VS

user@switch# set member 0 serial-number abc123 role routing-engine
user@switch# set member 1 serial-number def456 role routing-engine

serial numbers must be entered with UPPER CASE letters. I wish this was mentioned in the guide or at least the guide didn’t use lower case letters in the examples. Could’ve saved me a lot of time 🙁

Upgrading IOS XE on ASR 1002

So I needed to upgrade the IOS XE on customer’s ASR 1002 and after copying the image from USB to Flash, I issued a standard command

boot system flash asr1000rp1-advipservicesk9.03.16.03.S.155-3.S3-ext.bin

After reloading the router I get this error:

boot: unsupported boot device "asr1000rp1-advipservicesk9.03.16.03.S.155-3.S3-ext.bin"
autoboot: boot failed, restarting...

First Google search result showed that I missed ‘bootflash:‘ before the name of the IOS image and the correct command should be

boot system flash bootflash:asr1000rp1-advipservicesk9.03.16.03.S.155-3.S3-ext.bin

Definitely need to remember this 🙂

BE6000S Finally

Finally got my hands on BE6000S. An interesting little machine and worked great for the small project. One thing to keep in mind though, if you decide to change the default IP addresses, it’s better to rebuilt the BVI.
