* Only one EtherSwitch service module is supported in a platform when using the NME-XD-24ES-1S-P.

Q. How do I configure the EtherSwitch service modules?

A. The configuration of EtherSwitch service modules is done in two parts. First, configure the

router connection. This is an internal Gigabit Ethernet connection to the router backplane and

represents the logical connection between the switch modules and the router. Then issue the

session command to connect to the command-line interface (CLI) of the EtherSwitch service

module itself. At this point you may configure all of the ports and interfaces on the module.

For specific details on configuring selected switch features, see the Cisco IOS Software

12.2(25)EZ release notes. You can also configure and manage the EtherSwitch service

module using a combination of the Cisco Router and Security Device Manager (SDM) and

the embedded EtherSwitch device manager. Both of these tools come pre-installed by default.

Q. Do the EtherSwitch service modules work in the same platform as the existing

EtherSwitch network modules and HWICs?

A. Yes, you can use both the current EtherSwitch network modules and HWICs along with the

EtherSwitch service modules. Because they do not share a common VLAN database, you do

not need to connect the current EtherSwitch network modules with the new modules through

intrachassis stacking. However you must continue to use intrachassis stacking to connect two

of the current EtherSwitch network modules.

Because the EtherSwitch service modules are standalone switches on a blade, they do not

require intrachassis stacking, nor do they support it. Connectivity between the current

EtherSwitch network modules and the new service modules can be achieved in one of two

ways: either at Layer 3 through the router backplane, or over a trunking connection using an

external Ethernet cable. With the trunking approach, separate VLAN databases are

maintained for the EtherSwitch service module and the aggregation of current modules in the

platform. Because multiple VLAN database files are involved in the scenario described above,

VLAN Trunking Protocol (VTP) should be used for pruning VLANs between the databases.

Q. How many switch ports can I install in each platform?

A. Table 3 shows the maximum switch port densities in Cisco routers.
