Cisco ME-3600X IOS Upgrade Via archive download-sw Command

I often use the copy tftp flash command to perform an IOS upgrade on Cisco devices. The download software (from Cisco.com) for a Cisco ME-3600X switch is a .tar file, which is a compressed file that includes the .bin (bare image) and other HTML files.

The upgrade/downgrade of newer Cisco switch is now easier with the archive download-sw command. It's similar to the copy tftp flash command except that it will auto extract the .tar file, delete the existing .bin file and copy the new IOS.

We're using the ME switch as an aggregate Layer 3 switch for all Metro E client circuits. Most client router has Ethernet handoff and we don't need to keep on adding up Ethernet cards and schedule maintenance window on our PE routers. Here are some photos of the ME-3600X-24TS-M and the IOS upgrade procedure that I performed.

Configuring EtherChannel

We rarely use (or haven't used) EtherChannel in our data center core switches since we're running 1-GigabitEthernet and 10-GigabitEthernet fiber trunks all over the place. I always use the command below on a Nexus switch to check if the SFP/GBIC was detected and if the transmit (Tx) and receive (Rx) signals are within nominal range.

Cisco 7936 Conference Phone Default Password and Serial Number

I was doing a network inventory for one of our site remotely. I can't seem to login and get the serial number of a Cisco 7936 conference IP phone.  The default admin login is **# in order to access its web GUI. The MAC address is the same as the serial number.

The MAC address of the Cisco 7936 can be obtained via the Cisco Unified Communications Manager (CUCM) or Call Manager and under the Host Name portion on its web GUI.

Cisco 3650 PVLAN, Static VLANs, VLAN Trunking, VTP Domains and Modes

I was troubleshooting a Cisco 3650 Catalyst switch, which is their "new" line of stackable access switch, and I can't seem to get Private VLAN (PVLAN) to work. Cisco's data sheets were contradicting as to whether PVLAN is supported or not on this switch platform. I just couldn't believe this switch won't support this feature since its cousin switch like the 3750 and 3650 were using it. As I searched further, I found out that PVLAN is supported on IOS XE 3.7E but the IOS file was a bit large (around 300 MB).

It took me roughtly 40 minutes to TFTP the said IOS file on one switch. So I decided to try to configure the switch to use FTP instead. It took me around 3 mintues to upgrade the image.

Create the same username and password on the FTP client that is configured on the switch and point the folder directory where the IOS image was saved. I've used a free FTP client, which is 3CDaemon.

This was my first SWITCH lab that I did during my CCDP studies. The topology is a square looped design, which is very similar to the triangle loop design but there's a difference where STP blocking occurs.
