ERX7xx Models, ERX14xx Models, and the ERX310 Router

ERX7xx models, ERX14xx models, and the ERX310 router all support Service Modules
(SMs) and IPSec Service Modules (ISMs).
Unlike other line modules, SMs and ISMs do not pair with corresponding I/O modules
that provide ingress and egress ports. Instead, they receive data from and transmit
data to other line modules with ingress and egress ports.
See JUNOSe Release Notes, Appendix A, System Maximums for information about the
number of tunnels and sessions that each module supports.

E120 and E320 Routers

The E120 and E320 routers support the ES2-S1 Service IOA and ES2 4G line module
(LM) combination.
Unlike SMs and ISMs, you must install the ES2-S1 Service IOA with the ES2 4G LM
to use dedicated tunnel-server ports. The ES2-S1 Service IOA does not have ingress
and egress ports, but it conditions the ES2 4G LM to receive and transmit data to
other line modules.
See JUNOSe Release Notes, Appendix A, System Maximums for information about the
number of tunnels and sessions that the ES2-S1 Service IOA supports.

Supported Modules for Shared Tunnel-Server Ports

Most E Series routers support shared tunnel-server ports; however, the supported
modules depend on the type of E Series router that you have.
See JUNOSe Release Notes, Appendix A, System Maximums for information about the
number of tunnels and sessions that each module supports.

ERX14xx Models and the ERX310 Broadband Services Router

The ERX1440 and ERX310 routers support line modules on which you can use shared
tunnel-server ports. The following module combinations offer tunnel services in
addition to regular access services:
E120 and E320 Routers
The E120 and E320 routers support shared tunnel-server ports on the following line
module and IOA combinations:
