ERSPAN supported on "C9200L-24P-4G-E"

[Rasmus Kiilerich]

Hi

I got a new stack comprised of 2pc "C9200L-24P-4G-E" running 16.9.3

I´m trying to setup a ERSPAN as descried in the "Command Reference" document (linked below) however none of the need keyworks seems to be supported?!

Below are the output, showing the available keywords, on the switch when im trying to configure the ERSPAN destination part.

Am I missing anything here or are the command reference inaccurate?

C9200L(config)#monitor session 2 ?
destination SPAN destination interface or VLAN
filter SPAN filter VLAN
source SPAN source interface, VLAN

C9200L(config)#monitor session 2 destination remote ?
vlan Remote SPAN destination RSPAN VLAN

Hello,

what command are you looking for ? Once you enter 'remote' the only option is 'vlan'.

What is the full syntax you are looking for ?

Config im trying to apply

(Line 1) Switch# configure terminal
(Line 2) Switch(config)# monitor session 1 type erspan-source
(Line 3) Switch(config-mon-erspan-src)# source interface gigabitEthernet 1/0/23 rx
(Line 4) Switch(config-mon-erspan-src)# no shutdown
(Line 5) Switch(config-mon-erspan-src)# destination
(Line 6) Switch(config-mon-erspan-src-dst)# ip address <IP @ Wireshark PC>

Im trying to get past line 2 "monitor session 1 type erspan-source"

However the "type" are not a valid option.

This is my options

Switch(config)#monitor session 1 ?
destination SPAN destination interface or VLAN
filter SPAN filter VLAN
source SPAN source interface, VLAN

Hello,

what SDM template are you using (show sdm prefer) ? Whichever you are using, try to switch to the one your are NOT using (either 'vlan' or 'advanced') and reload the switch, then check if the option is available.

It is either the template, or a mistake in the documentation. The Nexus 9x switches do support the 'type'...

[Rasmus Kiilerich]

Huuumm.... running the Advanced template 

Will try to change the sdm on monday

Switch#show sdm prefer
Showing SDM Template Info

This is the Advanced template.
Number of VLANs: 1024
Unicast MAC addresses: 16384
Overflow Unicast MAC addresses: 256
L2 Multicast entries: 1024
L3 Multicast entries: 1024
Overflow L3 Multicast entries: 256
Directly connected routes: 8192
Indirect routes: 3072
STP Instances: 128
Security Access Control Entries: 1408
QoS Access Control Entries: 1024
Policy Based Routing ACEs: 512
Netflow Input ACEs: 128
Netflow Output ACEs: 128
Ingress Netflow ACEs: 128
Egress Netflow ACEs: 128
Flow SPAN ACEs: 256
Tunnels: 128
LISP Instance Mapping Entries: 128
Control Plane Entries: 512
Input Netflow flows: 8192
Output Netflow flows: 8192
SGT/DGT (or) MPLS VPN entries: 2048
SGT/DGT (or) MPLS VPN Overflow entries: 256
Wired clients: 2048
MACSec SPD Entries: 128
These numbers are typical for L2 and IPv4 features.
Some features such as IPv6, use up double the entry size;
so only half as many entries can be created.
* values can be modified by sdm cli.

The C9200 datasheet does not mention anything about ERSPAN that is supported, nor does it come in the release notes or in any of the release documentation, so it is not supported on this platform.

 - Seems you need at least a 9300 for ERSPAN , the attached document comes from the https://cfnng.cisco.com/
