Cisco Systems 8510 CSR, 8540 CSR appendix Configuring the POS OC-12c Uplink Interface Catalyst

Chapter 4 Configuring Interfaces

Configuring the POS OC-12c Uplink Interface (Catalyst 8540)

Figure 4-5shows an example of a service provider application of the POS OC-12c uplink interface module. Here traffic is aggregated from Catalyst 8500 CSRs over POS OC-12c interfaces to Cisco 12000 GSRs. POS OC-48 interfaces on the Cisco 12000 gigabit switch routers then provide the uplinks to the Internet backbone.

Configuring the POS OC-12c Uplink Interface (Catalyst 8540)

This section describes the default configuration of the POS OC-12c uplink interface, initial configurations you should perform for a newly installed interface, and optional configurations you can do to customize the interfaces to the requirements of your network.

Note The POS OC-12c uplink interface module consists of one OC-12c port and one enhanced Gigabit Ethernet port. For instructions on configuring the Gigabit Ethernet interface, see the “About the Enhanced Gigabit Ethernet Interfaces (Catalyst 8540)” section on page 4-5.
