Multidwelling Network Using the Cisco EtherSwitch Service Modules

A growing segment of residential and commercial customers is requiring high-speed access to Ethernet metropolitan-area networks (MANs). Figure 11 shows a configuration for a Gigabit Ethernet MAN ring using multilayer switch stacks as aggregation switches in the mini-point-of-presence (POP) location.

These switches are connected through 1000BASE-X SFP service module ports.

All ports on the residential service modules are configured as 802.1Q trunks with protected port and STP root guard features enabled. The protected port feature provides security and isolation between ports on the switch, ensuring that subscribers cannot view packets destined for other subscribers. STP root guard prevents unauthorized devices from becoming the STP root switch. All ports have IGMP snooping or CGMP enabled for multicast traffic management. ACLs on the uplink ports to the aggregating Catalyst 3750 multilayer switches provide security and bandwidth management.
