My Mobile Home Network Lab

So my lab allows me to login to a web page and power on/off all of my network gear. I also have a console server to remotely access every piece of gear. I use this lab extensively for building my Lynda and LinkedIn Learning videos. I also use it regularly for all sorts of network testing.

Everything is remotely accessible through the console server as well as remotely powered.
I have:
Cisco
– 7206 G1
– 2621XM
– 3550
– 3750G

Mikrotik:
-hap lite
-rb750

Digital logger power controlers
Avocent cyclades console server

Let me know what you guys do for your home lab!

OTRS To Gmail Failure

When trying to fetch email from Gmail into my OTRS install I saw the following error:

Facility:
OTRS-otrs.Console.pl-Maint::PostMaster::MailAccountFetch-19

CommunicationLog(ID:29,AccountType:-,AccountID:-,Direction:Incoming,Transport:Email,ObjectLogType:Connection,ObjectLogID:29)::Kernel::System::MailAccount::IMAP => IMAPS: Auth for user SomeRandomEmailAddress@gregsowell.com/imap.gmail.com failed!

First, log into your gmail account. Then go to “settings => forwarding and pop/imap” and enable imap.
Second, edit your account and set it to allow “less secure apps to use your account”.

You should now be able to properly fetch…good luck and happy ticketing 🙂

Set Jumbo Frames On A Nexus 3064

It is configured system wide to 9216 with the following commands:

4
5
6
7
policy-map type network-qos jumbo
class type network-qos class-default
mtu 9216
exit
exit
system qos
service-policy type network-qos jumbo

Verification is a bit odd, though. If you enter a standard show interface, it won’t show the correct value:

sw02# show int e1/1
Ethernet1/1 is down (SFP not inserted)

  reliability 255/255, txload 1/255, rxload 1/255
  Encapsulation ARPA
  Port mode is access

Notice how it has MTU displayed as “1500 bytes”.

If, however, I use the show queuing command it displays correctly:

    Pkts dropped by RX thresholds               : 0
    Bytes dropped by RX thresholds              : 0

Notice it shows “HW MTU: 9216”.
