Due to a very silly reason, my blog got deleted. I am trying to restore it gradually. Some posts I was able to salvage from old db backup, and some from the Web Archive. Others – from my drafts. I am not sure I will be restoring it completely, as not everything is relevant anymore.

So it finally happened to me – an MRA project with multiple domains. Previously I didn’t have to manually add entries to the ‘hosts’ file on Expressway, and needed to do some research. Here’s what came out of it:

‘A’ records are added to hosts.conf file which doesn’t exist by default and must be located at /tandberg/etc/dnsmasq.conf.d/. The screenshot below shows that it doesn’t exist (BTW, everything is done on Expressway version X12.6.2).

So I’ve had a problem with RONA where agents not picking up the call would be placed in ‘Not Ready – Call Not Answered’ state and, if there are no other available agents, placed back to ‘Ready’ again. The call would loop and go back-and-forth to this agent again and again.
Here is my configuration:

Agent Desk Setting had 8 seconds configured for Ring no answer time

CVP timeout timer was set to 12 seconds

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

The 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

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

Member’s information missing from provisioning database

Turns out, when adding members to VC

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 lowercase letters in the examples. It could’ve saved me a lot of time 🙁

So I needed to upgrade the IOS XE on the 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!
