Numbering Scheme
When configuring or managing tunnel-server ports, you must know the numbering
scheme for identifying the physical location of the port in the E Series router. The
numbering scheme depends on the type of E Series router that you have.
ERX7xx Models, ERX14xx Models, and the ERX310 Router
Use the slot/port format to identify dedicated and shared tunnel-server ports.
For information about installing tunnel-server modules in ERX routers, see ERX
Hardware Guide, Chapter 4, Installing Modules.
E120 and E320 Routers
Use the slot/adapter/port format to identify dedicated and shared tunnel-server ports.
ES2 4G LM with the ES2-S1 GE-4 IOA
ES2 4G LM with the ES2-S1 GE-8 IOA
ES2 4G LM with the ES2-S1 10GE IOA
ES2 4G LM with OCx/STMx ATM IOAs
ES2 4G LM with OCx/STMx POS IOAs
slot Number of the slot in which the tunnel-server module resides in the chassis
In ERX7xx models, line module slots are numbered 2-6; slots 0 and 1 are reserved
for SRP modules. In ERX14xx models, line module slots are numbered 0–5 and
8–13; slots 6 and 7 are reserved for SRP modules. In an ERX310 router, line
module slots are numbered 1–2; slot 0 is reserved for the SRP module.
port Number of the port on the tunnel-server module
For more information about identifying the port number on a tunnel-server port,
see "Configuring Tunnel-Server Ports and Tunnel-Service Interfaces" on page 225
.
slot Number of the slot in which the line module resides in the chassis
In the E120 router, line module slots are numbered 0–5. In the E320 router, line
module slots are numbered 0–5 and 11–16. For both routers, slots 6 and 7 are
reserved for SRP modules; slots 8–10 are reserved for switch fabric modules
(SFMs).
adapter—Number of the bay in which the I/O adapter (IOA) resides
This identifier applies to the E120 and E320 routers only. Dedicated tunnel-server
ports are supported on the ES2-S1 Service IOA, which is a full-height IOA and is
identified in the software as adapter 0. Shared tunnel-server ports reside on a
virtual adapter that is identified in the software as adapter 2.
port Number of the port on the IOA
For more information about identifying the port number on a tunnel-server port,
see "Configuring Tunnel-Server Ports and Tunnel-Service Interfaces" on page 225.
