Ease of Use and Ease of Deployment

• Auto-conﬁguration eases deployment of switches in the network by automatically conﬁguring multiple switches across

a network via a boot server.

• Auto-sensing on each non-GBIC port detects the speed of the attached device and automatically conﬁgures the port for

10-, 100-, or 1000-Mbps operation, easing the deployment of the switch in mixed 10, 100, and 1000BaseT environments.

• Auto-negotiating on all ports automatically selects half- or full-duplex transmission mode to optimize bandwidth.

• Cisco Discovery Protocol (CDP) Versions 1 and 2 enable a CiscoWorks network management station to automatically

discover the switch in a network topology.

• Cisco VTP supports dynamic VLANs and dynamic trunk conﬁguration across all switches.

• Support for dynamic VLAN assignment through implementation of VLAN Membership Policy Server (VMPS) client

functionality provides ﬂexibility in assigning ports to VLANs.

• Dynamic Trunking Protocol (DTP) enables dynamic trunk conﬁguration across all ports in the switch.

• Port Aggregation Protocol (PAgP) automates the creation of Cisco Fast EtherChannel® or Gigabit EtherChannel groups,

enabling linking to another switch, router, or server.

• IEEE 802.3z-compliant 1000BaseSX, 1000BaseLX/LH, 1000BaseZX, and 1000BaseT physical interface support

through a ﬁeld-replaceable GBIC module provides customers unprecedented ﬂexibility in switch deployment.

• The default conﬁguration stored in Flash ensures that the switch can be quickly connected to the network and can pass

trafﬁc with minimal user intervention.

• The switches support non-standard Ethernet frame sizes (mini-giants) up to 1542 bytes (conﬁgurations with GBIC ports

only).
