ES3528MV2 Supports RSPAN - A remote control mechanism that enhances traffic control and speeds up traffic-collecting Follow
Once a network system is set-up, administrators want to monitor and collect traffic if necessary. In the past, traffic is only allowed to be collected and analyzed in that DUT (Device under Testing). It would be much trouble if Duts are far away from office, for example, 100 miles away and distributed in several places.
RSPAN solves this problem. It is a remote control mechanism that does traffic-collecting not only on that Dut but those connected to Dut. Once testing switch is connected to remote switch, RSPAN copies the packages flowed in testing switch to the remote switch. In such way, administrators could monitor several different switches by just monitoring the traffic copied to the remote switch, and could stay in remote office without travelling hundred miles away.
ES3528MV2 is a L2 Fast Ethernet Standalone Switch. It supports RSPAN and speeds up traffic-collecting. Administrators could monitor the traffic by the following steps:
How to monitor the traffic of PC1 in a different VLAN of a remote switch ?
On Switch 1
1. Create VLAN 2
SW1(config)#vlan database
SW1(config-vlan)#vlan 2 media ethernet
2. Assign port 1 and port 2 to VLAN 2 access port
SW1(config)# interface ethernet 1/1-2
SW1(config-if)#switchport allowed vlan add 2
SW1(config)#switchport native vlan 2
SW1(config-if)#switchport allowed vlan remove 1
SW1(config)#exit
3. Enable RSPAN on VLAN 100
SW1(config)#vlan database
SW1(config-vlan)#vlan 100 media ethernet rspan
SW1(config-vlan)#exit
4. RSPAN Source device setting
SW1(config)#rspan session 1 source interface ethernet 1/1
SW1(config)#rspan session 1 remote vlan 100 source uplink ethernet 1/27
On Switch 2
1. Enable RSPAN on VLAN 100
SW2(config)#vlan database
SW2(config-vlan)#vlan 100 media ethernet rspan
SW2(config-vlan)#ex
2. RSPAN Destiatnion device setting
SW2(config)#rspan session 1 destination interface ethernet 1/1 tagged
SW2(config)#rspan session 1 remote vlan 100 destination uplink ethernet 1/27
How to verify the RSPAN function is working or not ?
