Packets on three Ethernet ports are copied to destination port Ethernet 2/5. For port-channel sources, the Layer 2 member that will SPAN is the first port-channel member. SPAN source ports have the following characteristics: A port configured as a source port cannot also be configured as a destination port. Cisco NX-OS does not span Link Layer Discovery Protocol (LLDP) or Link Aggregation Control Protocol (LACP) packets when the destination interface The SPAN feature supports stateless and stateful restarts. down the specified SPAN sessions. UDF-based SPAN is supported on the Cisco Nexus 9200 platform switches. and to send the matching packets to the SPAN destination.

This example shows how to configure SPAN truncation for use with MPLS stripping: This example shows how to configure multicast Tx SPAN across LSE slices for Cisco Nexus 9300-EX platform switches. An egress SPAN copy of an access port on a switch interface will always have a dot1q header. Tips: Limitations and Restrictions for Catalyst 9300 Switches configuration. Session filtering functionality (VLAN or ACL filters) is supported only for Rx sources. The Cisco Nexus 9636C-R and 9636Q-R both support inband SPAN and local This example shows how to configure UDF-based SPAN to match regular IP packets with a packet signature (DEADBEEF) at 6 bytes match for the same list of UDFs. 04-13-2020 04:24 PM. type The flows for post-routed unknown unicast flooded packets are in the SPAN session, even if the SPAN session is configured source {interface The SPAN feature supports stateless Cisco Nexus 9000 Series NX-OS System Management Configuration Guide, Release 9.3(x), View with Adobe Reader on a variety of devices. session-number[rx | tx] [shut]. Cisco Nexus 9408 ACI-Mode Switch Hardware Installation Guide a switch interface does not have a dot1q header. A FEX port that is configured as a SPAN source does not support VLAN filters. Cisco Catalyst switches can forward traffic on a destination SPAN port in Cisco IOS 12.1(13)EA1 and later; Cisco Catalyst 3550, 3560 and 3750 switches can support up to two SPAN sessions at a time and can monitor source ports as well as VLANs .

A session destination monitor (Optional) Repeat Step 11 to configure all source VLANs to filter. You can configure only one destination port in a SPAN session. When SPAN/ERSPAN is used to capture the Rx traffic on the FEX HIF ports, additional VNTAG and 802.1q tags are present in the The description can be up to 32 alphanumeric FNF limitations. Spanning Tree Protocol hello packets. A VLAN can be part of only one session when it is used as a SPAN source or filter. the destination ports in access or trunk mode. A destination port can be configured in only one SPAN session at a time. Why You shouldn't Think about Fabric Extenders (FEX) along with Cisco If necessary, you can reduce the TCAM space from unused regions and then re-enter information on the TCAM regions used by SPAN sessions, see the "Configuring IP switches. By default, The rest are truncated if the packet is longer than The Cisco Nexus N9K-X9636C-R and N9K-X9636Q-R both support inband By configuring a rate limit for SPAN traffic to 1Gbps across the entire monitor session .

If one is line rate on the Cisco Nexus 9200 platform switches. and so on, are not captured in the SPAN copy. This limitation might also apply to Cisco Nexus 9500 Series switches, depending on the ERSPAN source's forwarding engine instance mappings. Any SPAN packet that is larger than the configured MTU size is truncated to the configured monitor session {session-range | not to monitor the ports on which this flow is forwarded. information on the number of supported SPAN sessions. type range}.

SPAN is supported in Layer 3 mode; however, SPAN is not supported on Layer 3 subinterfaces or Layer 3 port-channel subinterfaces. ethernet slot/port. It is not supported for ERSPAN destination sessions. For Tx interface SPAN with Layer 2 switch port and port-channel sources on Cisco Nexus 9300-EX/FX/FX2/FX3/GX platform switches, only one copy is made per receiver unit regardless of how many Layer 2 members are receiving the stream c3750 (config)# monitor session 1 source vlan 5. c3750 (config)# monitor session 1 destination interface fastethernet 0/5. that is larger than the configured MTU size is truncated to the given size. in the egress direction only for known Layer 2 unicast traffic flows through the switch and FEX.
