This blog was originally started to better help me understand the technologies in the CCIE R&S blueprint; after completing the R&S track I have decided to transition the blog into a technology blog.

CCIE #29033

This blog will continue to include questions, troubleshooting scenarios, and references to existing and new technologies but will grow to include a variety of different platforms and technologies. Currently I have created over 185 questions/answers in regards to the CCIE R&S track!! Note: answers are in the comment field or within "Read More" section.

Remote Span - The ability to monitor ports that are distributed throughout the network on muliple switches.

Must create a VLAN which is used to send the traffic too.

"vlan 333"
"remote-span" - Must enter the remote-span command
"name remote-span vlan

The VLAN above should be able to traverse the trunk.

"monitor session #" is used to identify the source/destination pair you want to monitor and allows for multiple sessions

EX:

SWA

"vlan 333"
"remote-span"
"name remote-span vlan"
"interface fas 0/1"
"description TRUNK-SWB"
"switchport trunk encapsulation dot1q"
"switchport mode trunk"
"switchport trunk allowed vlan 333"
"interface fas 0/2"
"description TRUNK-SWC"
"switchport trunk encapsulation dot1q"
"switchport mode trunk"
"switchport trunk allowed vlan 333"
"monitor session 1 source vlan 333"
"monitor session 1 destination inter fas 0/10"

SWB

"vlan 333"
"remote-span"
"name remote-span vlan"
"interface fas 0/1"
"description TRUNK-SWA"
"switchport trunk encapsulation dot1q"
"switchport mode trunk"
"switchport trunk allowed vlan 333"
"monitor session 1 source vlan 50"
"monitor session 1 deatination remote vlan 333"

SWC


"vlan 333"
"remote-span"
"name remote-span vlan"
"interface fas 0/1"
"description TRUNK-SWA"
"switchport trunk encapsulation dot1q"
"switchport mode trunk"
"switchport trunk allowed vlan 333"
"monitor session 1 source inter fas 0/10 both"
"monitor session 1 deatination remote vlan 333"
