Features and Benefits of Cisco EtherSwitch Modules
Benefits
Delivers up to 200 Mbps of bandwidth (full duplex) Layer 2; forwards and filters backflow at full wire speed
on each port
Detects the speed of the attached device and automatically configures the port for 10- or 100-Mbps
operation
Provides fewer points of management for remote and small branch offices
Supports QoS based on the Institute of Electrical and Electronics Engineers (IEEE) class-of-service (CoS)
and port-based prioritization, allowing the switch to change the CoS settings of tagged packets on a per-port
basis
Allows the setup of separate VLANs with tagged and untagged framing; trunking is used to save ports when
creating a link between two devices implementing VLANs
Simplifies network configuration and improves fault tolerance
Enables phones to be placed into their own VLANs without the need for end-user intervention; a user can
plug the phone into the switch, and the switch provides the phone with the necessary VLAN information
Enables users to prioritize mission-critical traffic, such as VoIP and IP-based video applications over regular
traffic
Prevents unauthorized stations from accessing the switch; Cisco fully supports the entire set of Requests for
Comments (RFCs)
Provide a comprehensive and convenient visual management system
Provides configuration through Cisco IOS CLI and provides common user interface for all the router
functions
Offers Internet Group Management Protocol (IGMP) snooping in hardware for management support
Features 4-/8-MB shared-memory architecture that is shared across all ports
Offers support for Simple Network Management Protocol (SNMP) Management Information Base (MIB)
manageable via a MIB browser
EtherSwitch with the external power chassis or internal power supply upgrades can power Cisco IP Phones
and wireless access points
Allows external connections to other switches and Gigabit Ethernet file servers. Required for intra-chassis
stacking of modules
