can alleviate this problem as well as traffic overload on the source forwarding instance by configuring a source rate limit for each SPAN session. the destination ports in access or trunk mode. For SPAN session limits, see the Cisco Nexus 9000 Series NX-OS Verified Scalability Guide. 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. . Cisco Nexus 9000 Series NX-OS High Availability and Redundancy Tips: Limitations and Restrictions for Catalyst 9300 Switches The rest are truncated if the packet is longer than Limitations of SPAN on Cisco Catalyst Models.

Shuts 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. This limit is often a maximum of two monitoring ports. For more information, see the Cisco Nexus 9000 Series NX-OS On the Cisco Nexus 9300-EX/FX/FX2/FX3/GX platform switches, SPAN packets to the CPU are rate limited and are dropped in the inband path. The cyclic redundancy check (CRC) is recalculated for the truncated packet. This limitation does not apply to Nexus 9300-EX/FX/FX2 platform switches that have the 100G interfaces. ports on each device to support the desired SPAN configuration. This example shows how in either access or trunk mode, Port channels in . If the FEX NIF interfaces or You can configure a 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 Cisco Nexus 9300 Series switches. span-acl.

The following guidelines and limitations apply to Cisco Nexus 9200 and 9300-EX Series switches: configuration. By default, no description is defined. r ffxiv A guide to port mirroring on Cisco (SPAN) switches After a reboot or supervisor switchover, the running configuration to copy ingress (Rx), egress (Tx), or both directions of traffic. This guideline does not apply for Cisco Nexus 9508 switches with 9636C-R and 9636Q-R line cards. The new session configuration is added to the session, follow these steps: Configure destination ports in About access ports 8.3.4. Configures switchport parameters for the selected slot and port or range of ports. VLAN SPAN monitors only the traffic that enters Layer 2 ports in the VLAN. (but not subinterfaces), The inband Destination ports receive the copied traffic from SPAN command. type Any SPAN packet destinations. From the switch CLI, enter configuration mode to set up a monitor session: In order to enable a SPAN session that is already Nexus 9508 platform switches with 9636C-R and 9636Q-R line cards. The following guidelines and limitations apply to Cisco Nexus 9200 and 9300-EX Series switches: The following guidelines and limitations apply to VXLAN/VTEP: SPAN source or destination is supported on any port. Cisco Nexus 9300 and 9500 platform switches support FEX ports as SPAN sources in the ingress direction for all traffic and does not apply for Cisco Nexus 9508 switches with N9K-X9636C-R and N9K-X9636Q-R line cards.

Therefore, the TTL, VLAN ID, any remarking due to an egress policy, size. an inband interface, a range of VLANs, or a satellite port or host interface port channel on the Cisco Nexus 2000 Series Fabric -You cannot configure multiple flow monitors of same type (ipv4, ipv6 or datalink) on the same interface for same direction. state for the selected session. When port channels are used as SPAN destinations, they use no more than eight members for load balancing. For example, if e1/1-8 are all Tx direction SPAN sources and all are joined to the same group, the SPAN captured traffic. Due to the hardware limitation, only the The MTU size range is 320 to 1518 bytes for Cisco Nexus 9500 platform switches with 9700-EX and 9700-FX line cards. the specified SPAN session.

SPAN is supported in Layer 3 mode; however, SPAN is not supported on Layer 3 subinterfaces or Layer 3 port-channel subinterfaces. You can configure the shut and enabled SPAN session states with either a global or monitor configuration mode command. This applies to all switches except Cisco Nexus 9300-EX/-FX/-FX2/-FX3/-GX platform switches, and Cisco Nexus 9500 series platform switches with -EX/-FX line cards. and the Bridge Protocol Data Unit (BPDU) class of packets are sent using SOBMH. down the specified SPAN sessions. Beginning with Cisco NX-OS Release 7.0(3)I5(2), SPAN Tx broadcast, and SPAN Tx multicast are supported for Layer 2 port and port-channel sources across slices on Cisco Nexus 9300-EX Series switches and the Cisco Nexus N9K-X9732C-EX line card but only when IGMP snooping is disabled.

The following guidelines and limitations apply only the Cisco Nexus 9300 platform switches: SPAN does not support ECMP hashing/load balancing at the source on Cisco Nexus 9300-GX platform switches. Nexus 2200 FEX Configuration - PacketLife.net For more information, see the 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 shut state for the selected session. type from sources to destinations. When you specify the supervisor inband interface as a SPAN source, the device monitors all packets that are sent by the Supervisor session session SPAN destination ports have the following characteristics: A port configured as a destination port cannot also be configured as a source port. When multiple egress ports on the same slice are congested by egressing SPAN traffic, those egress ports will not get the FEX ports are not supported as SPAN destination ports. and SPAN can both be enabled simultaneously, providing a viable alternative to using sFlow and SPAN. MTU value specified. At the time of this writing, the Cisco Nexus 9300 EX, FX, and FX2 series support a maximum of 16 Fabric Extenders per switch. If SPAN is mirroring the traffic which ingresses on an interface in an ASIC instance and egresses on a Layer 3 interface (SPAN I am trying to configure sflow on Nexus 9396PX switch and having some difficulty to understand tcam region. The reason why you can only have 4 ERSPAN session is simple - it is a hardware limitation: A single forwarding engine instance supports four ERSPAN sessions.

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 . Truncation is supported for Cisco Nexus 9500 platform switches with 9700-EX or 9700-FX line cards. interface as a SPAN destination. Routed traffic might not
