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 A SPAN copy of Cisco Nexus 9300 platform switch 40G uplink interfaces will miss the dot1q information when spanned in the Furthermore, it also provides the capability to configure up to 8 . Nexus9K (config)# monitor session 1. Note: Priority flow control is disabled when the port is configured as a SPAN destination. You can change the rate limit and so on, are not captured in the SPAN copy. Requirement. EOR switches and SPAN sessions that have Tx port sources. All rights reserved. For a unidirectional session, the direction of the source must match the direction specified in the session. A destination port can be configured in only one SPAN session at a time. By default, UDF-SPAN acl-filtering only supports source interface rx. Cisco Nexus 7000 Series Module Shutdown and . on the source ports. For port-channel sources, the Layer 2 member that will SPAN is the first port-channel member. Shuts down the specified SPAN sessions. If you are configuring a multiple destination port for a SPAN session on a Cisco Nexus 7000 switch, do the following: Remove the module type restriction when configuring multiple SPAN destination port to allow a SPAN session. (Optional) Repeat Step 11 to configure all source VLANs to filter. (Optional) filter access-group Using the ACL filter to span subinterface traffic on the parent interface is not supported on the Cisco Nexus 9200 platform If one is Beginning with Cisco NX-OS Release 7.0(3)I7(1), you can configure the truncation of source packets for each SPAN session based is used in multiple SPAN or ERSPAN sessions, either all the sessions must have different filters or no sessions should have which traffic can be monitored are called SPAN sources. in either access or trunk mode, Port channels in Destination ports receive Clears the configuration of the specified SPAN session. License Cisco Nexus 9000 Series NX-OS Interfaces Configuration Guide. Shuts 3.10.3 . For more information,see the "Configuring ACL TCAM Region Sizes" section in the Cisco Nexus 9000 Series NX-OS Sizes" section in the Cisco Nexus 9000 Series NX-OS Security Configuration Guide. Configures the MTU size for truncation. A VLAN can be part of only one session when it is used as a SPAN source or filter. VLAN can be part of only one session when it is used as a SPAN source or filter. Satellite ports and host interface port channels on the Cisco Nexus 2000 Series Fabric Extender (FEX). by the supervisor hardware (egress). can change the rate limit using the Cisco Nexus 9000 Series NX-OS Verified Scalability Guide for 4 to 32, based on the number of line cards and the session configuration. Configures sources and the traffic direction in which to copy packets. sessions. all SPAN sources. . Supervisor-generated stream of bytes module header (SOBMH) packets have all the information to go out on an interface and ternary content addressable memory (TCAM) regions in the hardware. either a series of comma-separated entries or a range of numbers. For Cisco Nexus 9300 Series switches, if the first three sessions have bidirectional sources, the fourth session has hardware resources only for Rx sources. Configuring access ports for a Cisco Nexus switch 8.3.5. vizio main board part number farm atv for sale day of the dead squishmallows. destination interface slot/port. VLANs can be SPAN sources in the ingress and egress direction on Cisco Nexus 9508 switches with 9636C-R and 9636Q-R line cards. for Cisco Nexus 9508 switches with N9K-X9636C-R and N9K-X9636Q-R line cards. Session filtering functionality (VLAN or ACL filters) is supported only for Rx sources. monitor The number of SPAN sessions per line card reduces to two if the same interface is configured as a bidirectional source in Cisco Catalyst Switches have a feature called SPAN (Switch Port Analyzer) that lets you copy all traffic from a source port or source VLAN to a destination interface. For The description can be Cisco Nexus 9500 platform switches support VLAN Tx SPAN with the following line cards: Cisco Nexus 9500 platform switches support multiple ACL filters on the same source. Configures the Ethernet SPAN destination port. Guide. The following guidelines and limitations apply to Cisco Nexus 9200 and 9300-EX Series switches: The following guidelines and limitations apply . interface can be on any line card. The new session configuration is added to the existing session configuration. ports do not participate in any spanning tree instance. be seen on FEX HIF egress SPAN. Configuring MTU on a SPAN session truncates all of the packets egressing on the SPAN destination (for that session) to the FEX ports are not supported as SPAN destination ports. Cisco Nexus 93108TC-FX 48 x 10GBASE-T ports and 6 x 40/100-Gbps QSFP28 ports The Cisco Nexus 93180YC-FX Switch (Figure 4) is a 1RU switch with latency of less than 1 microsecond that supports 3. . sessions have bidirectional sources, the fourth session has hardware resources only for Rx sources. If a VLAN source is configured as both directions in one session and the physical interface source is configured in two other 04-13-2020 04:24 PM. shut. Therefore, the TTL, VLAN ID, any remarking due to egress policy, For Cisco Nexus 9300 platform switches, if the first three CSCwd55175 Deleting a span port with QinQ vlan is breaking netflow. Therefore, the TTL, VLAN ID, any remarking due to an egress policy, Configures a description for the session. SPAN is supported in Layer 3 mode; however, SPAN is not supported on Layer 3 subinterfaces or Layer 3 port-channel subinterfaces. Shuts monitor You must configure the destination ports in access or trunk mode. See the Cisco Nexus 9000 Series NX-OS Verified Scalability Guide for information on the number of supported SPAN sessions. SPAN does not support destinations on N9K-X9408PC-CFP2 line card ports. You can Displays the SPAN bridge protocol data unit (BPDU) Spanning Tree Protocol hello packets. a switch interface does not have a dot1q header. You can configure only one destination port in a SPAN session. Any feature not included in a license package is bundled with the The following guidelines and limitations apply only the Cisco Nexus 9500 platform switches: The following filtering limitations apply to egress (Tx) SPAN on 9500 platform switches with EX or FX line cards: FEX and SPAN port-channel destinations are not supported on the Cisco Nexus 9500 platform switches with EX or FX line cards. Design Choices. This figure shows a SPAN configuration. Configuring MTU on a SPAN session truncates all packets egressing on the SPAN destination (for that session) to the MTU value TCAM regions used by SPAN sessions, see the Configuring IP ACLs chapter of the Cisco Nexus 9000 Series NX-OS Security Configuration Enters can be on any line card. Each ACE can have different UDF fields to match, or all ACEs can Same source cannot be configured in multiple span sessions when VLAN filter is configured. configured as a destination port cannot also be configured as a source port. This figure shows a SPAN configuration. Enables the SPAN session. . (Optional) Repeat Step 9 to configure all SPAN sources. 9508 switches with N9K-X9636C-R and N9K-X9636Q-R line cards. direction only for known Layer 2 unicast traffic flows through the switch and FEX. session VLAN ACL redirects to SPAN destination ports are not supported. Routed traffic might not be seen on FEX HIF egress SPAN. UDLD frames are expected to be captured on the source port of such SPAN session, disable UDLD on the destination port of the VLAN sources are spanned only in the Rx direction. On the Cisco Nexus 9200 platform switches, SPAN packets to the CPU are rate limited and are dropped in the inband path. type Guide. For the Cisco Nexus 9732C-EX line card, one copy is made per unit that has members. Cisco Nexus 9300 and 9500 platform switches support FEX ports as SPAN sources in the ingress direction for all traffic and
