Ethernet Service Instance (ESI) overview

•
Client ESI - An ESI that is defined to be a client of another ESI, and that can have one or more
VLANs defined inside it.
Configuration considerations
The following rules apply for CLI operations for Provider Bridge (PB) and related protocols:
•
To prevent topology changes at startup, it is recommended that you not use the same ESI-Vlan
ID as the Default-Vlan ID.
•
An ESI is created for each service (such as a customer CVLANs, SVLANs, PBB, etc.).
•
All attributes for an ESI - such as VLAN, port binding, encapsulation, etc., are defined inside an
ESI.
•
To prevent configuration errors, no parameter overrides are permitted outside of an ESI.
•
ESIs can be nested to provide multiple protocol encapsulations for a packet. Restrictions on
bindings can be present depending on the actual platform. When nesting is used, inner ESIs
are called client ESIs.
•
A given VLAN means CVLAN or SVLAN, depending on the encapsulation definition for the ESI:
•
If no encapsulation is defined as “cvlan” the VLAN refers to CVLAN.
NOTE
For ESI VLANs, It is mandatory to define an encapsulation.
•
If encapsulation is “svlan”, the VLAN refers to SVLAN (PB).
•
If encapsulation is “bvlan”, the VLAN refers to B-VLAN (PBB).
•
ISID values are treated differently from other VLANs, since ISID parameters have no networking
association and are used only for mapping different SVLANs into service identifiers.
Creating an ESI
Create an ESI by naming it and specifying encapsulation type for all the VLANs inside it.
Creating an ESI with CVLAN tagging
To create an ESI with CVLAN tagging named “acme”, enter a command such as the following.
Brocade (config)# esi acme encapsulation cvlan
Syntax: [no] esi esi-name encapsulation cvlan | svlan | isid | bvlan
Use the cvlan parameter to specify the encapsulated customer VLAN (CVLAN).
Use the svlan parameter to specify the encapsulated service VLAN (SVLAN).
Use the isid parameter to specify the encapsulation for the mapping of SVLANs into service
identifiers.
Use the bvlan parameter to specify the encapsulated backbone VLAN (BVLAN).
Once an ESI is created, subsequent invocations of the ESI do not require the encapsulation
parameter.
