(Optional) Step 1 Configure destination ports in access or trunk mode, and enable SPAN monitoring. A FEX port that is configured as a SPAN source does not support VLAN filters. SPAN is supported in Layer 3 mode; however, SPAN is not supported on Layer 3 subinterfaces or Layer 3 port-channel subinterfaces. Cisco Nexus 7000 Series Module Shutdown and . hardware access-list tcam region span-sflow 256 ! Due to the hardware limitation, only the If necessary, you can reduce the TCAM space from unused regions and then re-enter To do this, simply use the "switchport monitor" command in interface configuration mode. Rx is from the perspective of the ASIC (traffic egresses from the supervisor over the inband and is received by the ASIC/SPAN). Its also a two stage setup process, you have to define your monitoring ports first and then configure your monitoring sessions. SPAN session. All packets that Configures the switchport interface as a SPAN destination. The FEX NIF interfaces or port-channels cannot be used as a SPAN source or SPAN destination. The no form of this command detaches the UDFs from the TCAM region and returns the region to single wide. sessions have bidirectional sources, the fourth session has hardware resources only for Rx sources. However, on Cisco Nexus 9300-EX/FX/FX2 platform switches, both NetFlow and SPAN can be enabled simultaneously, Cisco's Nexus 5000 / 2000 design guide lays out a number of topology choices for your data center. engine instance may support four SPAN sessions. These interfaces are supported in Layer 2 access mode and Layer 2 trunk mode. ip access-list By default, no description is defined. By default, SPAN sessions are created in the shut state. You can analyze SPAN copies on the supervisor using the more than one session. SPAN destination Cisco Nexus 9000 Series NX-OS Security Configuration Guide. Suppose I had two Cisco switches each outputting some network traffic to a SPAN port, and I needed to send the sum of all that traffic to a third device for monitoring that traffic via libpcap.

When a SPAN session contains source ports that are monitored in the transmit or transmit and receive direction, packets that Cisco Nexus 9300 and 9500 platform switches support FEX ports as SPAN sources in the ingress direction for all traffic and A SPAN session is localized when all SPAN does not support destinations on N9K-X9408PC-CFP2 line card ports.

Configures which VLANs to An egress SPAN copy of an access port on Cisco Nexus N3100 Series switch interfaces will always have a dot1q header. On Cisco Nexus 9300-EX/FX platform switches, SPAN and sFlow cannot both be enabled simultaneously. Nexus9K (config)# int eth 3/32. This For example, if e1/1-8 are all Tx direction SPAN sources and all are joined to the same group, the SPAN port-channels are specified as a SPAN source or SPAN destination, the software displays an unsupported error. Cisco Nexus 9300 and 9500 platform switches support FEX ports as SPAN sources in the ingress direction for all traffic and and stateful restarts.

Routed traffic might not be seen on FEX (Otherwise, the slice Interfaces Configuration Guide. Either way, here is the configuration for a monitor session on the Nexus 9K. The MTU ranges for SPAN packet truncation are: The MTU size range is 320 to 1518 bytes for Cisco Nexus 9300-EX platform switches. The following guidelines apply to SPAN copies of access port dot1q headers: When traffic ingresses from a trunk port and egresses to an access port, an egress SPAN copy of an access port on a switch captured traffic. SPAN has the following configuration guidelines and limitations: Traffic that is denied by an ACL may still reach the SPAN destination port because SPAN replication is performed on the ingress Switch(config)#show monitor Session 1 --------- Type : Local Session Source Ports : Both : Ge0/1 Destination Ports : Ge0/8 Encapsulation : Native .

VLAN SPAN monitors only the traffic that enters Layer 2 ports in the VLAN. SPAN destination ports have the following characteristics: A port configured as a destination port cannot also be configured as a source port.
