Let’s check if it’s available on our switches: To be honest this may be also platform dependent, someone has reported to be able to do this (having multiple sources on the path) but when using all C6500 switches. switchport trunk encapsulation dot1q <-- this might or might not be required. RSPAN is an advanced feature that requires a special VLAN to carry the traffic that is monitored by SPAN between switches. The connections between our switches and the core switch are access ports, which means the normal Cisco configuration for setting up RSPAN is not available since it requires trunking VLANs over the connection, something we're not able to do without access to the core switch. 2) Configuring RSPAN: Step 1: In order to configure RSPAN you need to have an RSPAN VLAN, those VLANs have special properties and can’t be assigned to any access ports. Configure an RSPAN port group and set the RSPAN VLAN tag of 901, which we configured on the Cisco Switch previously. Cisco SPAN port is a SwitchPort ANalyzer on the cisco catalyst that allows to select and span or copy traffic from one or more source switchports or source VLANs onto one or more destination ports. RSPAN enables an extension of a SPAN over the network to another switch on a Layer-2 nonroutable RSPAN VLAN. SPAN session 2 only monitors egress traf A special VLAN type must be used as the RSPAN destination. Source and destination of target traffic is on the same local switch, configuration is straightforward. set rspan destination {mod_num/port _ num} {rspan _ vlan} [inpkts {enable | disable}] [learning {enable | disable}] [create] Step 2 . All devices behind the switch were still up and active, we only lost management access of the switch, rebooting the switch resolved the issue. 15. There are three types SPAN.These are: Local SPAN (SPAN), Remote SPAN (RSPAN) and Encapsulated Remote SPAN (ERSPAN). #destination interface ethernet [port] To learn more about configuring port mirroring for the Cisco Nexus device, refer to the Configuring SPAN section of the Cisco Nexus 5000 Series NX-OS Software Configuration Guide on the vendor website. A. Bạn có thể giám sát mạng hiệu quả thông qua một cổng bằng cách sử dụng Switched Port Analyzer (SPAN). A special VLAN type must be used as the RSPAN destination. A RSPAN VLAN is created first. RSPAN encapsulates SPAN traffic in a VLAN tag, permitting its encapsulation across VLAN trunk links between switches. Hello, as far as I recall, the native Vlan does not have to be explicitly allowed on the trunk. Remote SPAN (RSPAN) RSPAN VLANs are also a special “type” of VLANs. switchport trunk native vlan 40. switchport trunk allowed vlan 10,20,30.
