Nexus 3000 SPAN RSPAN ERSPAN

[Nils 86]

hello,

i want to monitor (SPAN) some ports on our nexus31108PCV to another nexus switch. 
On most catalyst switches i can use RSPAN to monitor the traffic into an remote span vlan.
the nexus doesn´t support RSPAN but i can use ERSPAN but only as the source?! 

switch1(config)# monitor session 10 type ?
erspan-source            Create an erspan source session
local                            Create a local session

is there another feature that i can use for monitoring or will the rspan feature come to the nexus 3000?

thanks for your replays, sorry for my englisch :)

Hi Nils,

The Cisco NX-OS system supports the Encapsulated Remote Switching Port Analyser (ERSPAN) feature on both source and destination ports. ERSPAN transports mirrored traffic over an IP network. The traffic is encapsulated at the source router and is transferred across the network. The packet is decapsulated at the destination router and then sent to the destination interface.

ERSPAN consists of an ERSPAN source session, routable ERSPAN generic routing encapsulation (GRE)-encapsulated traffic, and an ERSPAN destination session.

You can find the config details here

Hi Nils,

It will work in one of the 7.0(3)I4(x) releases, you can upgrade and test it.

hi Manisch,

another switch is running with 7.0(3)I4(6), but it is the same scenario.

there is only the command with source:

C3100S20_201(config)# monitor session 10 type ?
erspan-source     Create an erspan source session
local                    Create a local session

C3100S20_201(config)# monitor session 10 type

Hi Nils,

Looking into a couple of TAC cases i can see that this feature is not available on Nexus 3K yet, however there is no bug id to clearly document the same as the guides show that this can be configured. I would suggest checking with TAC if you need more details and also the possibility of this getting fixed in any upcoming versions.

I have the same problem and I see the last post here was 6 months ago. Can you tell me if it has been fixed yet?
