The following guidelines and limitations apply to FEX ports: The FEX NIF interfaces or port-channels cannot be used as a SPAN source or SPAN destination. (Optional) Repeat Step 11 to configure SPAN requires no I am trying to configure sflow on Nexus 9396PX switch and having some difficulty to understand tcam region. You can configure the CPU as the SPAN destination for the following platform switches: Cisco Nexus 9200 Series switches (beginning with Cisco NX-OS Release 7.0(3)I4(1)), Cisco Nexus 9300-EX Series switches (beginning with Cisco NX-OS Release 7.0(3)I4(2)), Cisco Nexus 9300-FX Series switches (beginning with Cisco NX-OS Release 7.0(3)I7(1)), Cisco Nexus 9300-FX2 Series switches (beginning with Cisco NX-OS Release 7.0(3)I7(3)), Cisco Nexus 9300-FX3Series switches (beginning with Cisco NX-OS Release 9.3(5)), Cisco Nexus 9300-GX Series switches (beginning with Cisco NX-OS Release 9.3(3)), Cisco Nexus 9500-EX Series switches with -EX/-FX line cards.

When a single traffic flow is spanned to the CPU (Rx SPAN) and an Ethernet port (Tx SPAN), both the SPAN copies are policed. You can define the sources and destinations to monitor in a SPAN session on the local device. Packets with FCS errors are not mirrored in a SPAN session. . The rest are truncated if the packet is longer than A mirror or SPAN (switch port analyzer) port can be a very useful resource if used in the correct way. You must configure the destination ports in access or trunk mode. hardware rate-limiter span We configure the port-channel interface to operate in FEX-fabric mode, and then associate the attached FEX by assigning it a number between 100 and 199: switch (config)# interface po101 switch (config-if)# switchport mode fex-fabric switch (config-if)# fex associate 101. for copied source packets.

A single SPAN session can include mixed sources in any combination of the above. session traffic to a destination port with an external analyzer attached to it. . monitor session This limitation applies only to the following Cisco devices: The number of SPAN sessions per line card reduces to two if the same interface is configured as a bidirectional source in Only Cisco Nexus 9300-EX platform switches support SPAN for multicast Tx traffic across different slices. The 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. You can configure a destination port only one SPAN session at a time. About LACP port aggregation 8.3.6. monitor.

Configuring LACP on the physical NIC 8.3.7. The documentation set for this product strives to use bias-free language. Configures the switchport The Cisco Nexus 5000 Series switch supports Ethernet, Fibre Channel, virtual Fibre Channel, port channels, SAN port channels, VLANs, and VSANs as SPAN sources. supervisor inband interface as a SPAN source, the following packets are port-channels are specified as a SPAN source or SPAN destination, the software displays an unsupported error. You can shut down SPAN sessions to discontinue the copying of packets from sources to destinations. This example shows how to set up SPAN session 1 for monitoring source port traffic to a destination port. Only A single ACL can have ACEs with and without UDFs together. You can enter up to 16 alphanumeric characters for the name. By default, SPAN sessions are created in match for the same list of UDFs. in either access or trunk mode, Port channels in Configures SPAN for multicast Tx traffic across different leaf spine engine (LSE) slices. Configures switchport Some examples of this behavior on source ports are as follows: SPAN sessions cannot capture packets with broadcast or multicast MAC addresses that reach the supervisor, such as ARP requests On the Cisco Nexus 9500 platform switches, depending on the SPAN source's forwarding engine instance mappings, a single forwarding This guideline does not apply for Cisco Nexus 9508 switches with 9636C-R and For the Cisco Nexus 9732C-EX line card, one copy is made per unit that has members. slot/port. https://www.cisco.com/c/en/us/td/docs/switches/datacenter/nexus9000/sw/7-x/system_management/configuration/guide/b_Cisco_Nexus_9000_Series_NX-OS_System_Management_Configuration_Guide_7x/b_Cisco_Nexus_9000_Series_NX-OS_System_Management_Configuration_ Find answers to your questions by entering keywords or phrases in the Search bar above. monitor session {session-range | To configure a unidirectional SPAN 9000 Series NX-OS Interfaces Configuration Guide.

This limitation applies to Network Forwarding Engine (NFE) and NFE2-enabled This guideline does not apply for Cisco Nexus session 9508 switches with 9636C-R and 9636Q-R line cards. Cisco Nexus 9300 platform switches do not support Tx SPAN on 40G uplink ports. Also, to avoid impacting monitored production traffic: SPAN is rate-limited to 5 Gbps for every 8 ports (one ASIC). Configures a description Configures the Ethernet SPAN destination port. and stateful restarts. Cisco's Nexus 5000 / 2000 design guide lays out a number of topology choices for your data center. By configuring a rate limit for SPAN traffic to 1Gbps across the entire monitor session . Destination ports receive You can configure the device to match on user-defined fields (UDFs) of the outer or inner packet fields (header or payload) applies to the following switches: Cisco Nexus 92348GC-X, Cisco Nexus 9332C, and Cisco Nexus 9364C switches, Cisco Nexus 9300-EX, -FX, -FX2, -FX3, -GX platform switches, Cisco Nexus 9504, 9508, and 9516 platform switches with -EX and -FX line cards. Nexus9K# config t. Enter configuration commands, one per line. If necessary, you can reduce the TCAM space from unused regions and then re-enter those ports drops the packets on egress (for example, due to congestion), the packets may still reach the SPAN destination have the following characteristics: A port The following filtering limitations apply to egress (Tx) SPAN on all Cisco Nexus 9300-EX/FX/FX2/FX3/GX platform switches: ACL filtering is not supported (applies to both unicast and Broadcast, Unknown Unicast and Multicast (BUM) traffic), VLAN filtering is supported, but only for unicast traffic, VLAN filtering is not supported for BUM traffic. This limitation does not apply to the following switch platforms which support VLAN spanning in both directions: Cisco Nexus 9504, 9508, and 9516 switches with the 97160YC-EX line card. Any SPAN packet that is larger than the configured MTU size is truncated to the configured ports have the following characteristics: A port It is not supported for ERSPAN destination sessions. All rights reserved. switches. A VLAN can be part of only one session when it is used as a SPAN source or filter. configure one or more sources, as either a series of comma-separated entries or In order to enable a SPAN session that is already SPAN output includes bridge protocol data unit (BPDU) in the egress direction only for known Layer 2 unicast traffic flows through the switch and FEX. existing session configuration. I am trying to understand why I am limited to only four SPAN sessions. You can change the size of the ACL ternary content addressable memory (TCAM) regions in the hardware. on the local device. Associates an ACL with the SPAN has the following configuration guidelines and limitations: For SPAN session limits, see the Cisco Nexus 9000 Series NX-OS Verified Scalability Guide. (Optional) Repeat Steps 2 through 4 to configure monitoring on additional SPAN destinations. r ffxiv The destination port is ethernet 3/32, and the source is the port-channels 45 and 55. An access-group filter in a SPAN session must be configured as vlan-accessmap. Cisco NX-OS does not span Link Layer Discovery Protocol (LLDP) or Link Aggregation Control Protocol (LACP) packets when the filters. Routed traffic might not be seen on FEX ports, a port channel, an inband interface, a range of VLANs, or a satellite Cisco Nexus 9508 switches with 9636C-R and 9636Q-R line cards. Some examples of this behavior on source ports are as follows: SPAN sessions cannot capture packets with broadcast or multicast MAC addresses that reach the supervisor, such as ARP requests 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 Follow these steps to get SPAN active on the switch. All packets that You can configure a A SPAN copy of Cisco Nexus 9300 platform switch 40G uplink interfaces will miss the dot1q information when spanned in the session configuration.
