At this moment, it is not possible to emulate Catalyst switches with Dynamips/GNS3. This is due to the impossibility to emulate ASIC processors used in those type of devices. However you can use the EtherSwitch module with 2600s, 3600s and 3700s Series. Keep in mind that this module works differently (uses the vlan database etc.) and doesn’t support the following features:Access Switch Device Manager (SDM) Template ACL – Improved Merging Algorithm ARP Optimization BGP Increased Support of Numbered as-path Access Lists to 500 BGP Restart Neighbor Session After max-prefix Limit Reached BGP Route-Map Continue Support for Outbound Policy Clear Counters Per Port DHCP Snooping DHCP Snooping Counters Diagnotics Options on bootup ErrDisable Reactivation Per Port ErrDisable timeout EtherChannel – Flexible PAgP Etherchannel Guard Fallback Bridging Flex Link Bi-directional Fast Convergence Flex Link VLAN Load-Balancing Flex Links Interface Preemption GOLD – Generic Online Diagnostics IEEE 802.1ab, Link Layer Discovery Protocol IEEE 802.1s – Multiple Spanning Tree (MST) Standard Compliance IEEE 802.1s VLAN Multiple Spanning Trees IEEE 802.1t IEEE 802.1W Spanning Tree Rapid Reconfiguration IEEE 802.1x – Auth Fail Open IEEE 802.1x – Auth Fail VLAN IEEE 802.1x – VLAN Assignment IEEE 802.1x – Wake on LAN Support IEEE 802.1X Multi-Domain Authentication IEEE 802.1x RADIUS Accounting IEEE 802.1x with Port Security IEEE 802.3ad Link Aggregation (LACP) IEEE 802.3af Power over Ethernet IGMP Fast Leave IGMP Version 1 IGRP IP Phone Detection Enhancements IP Phone Enhancement – PHY Loop Detection IPSG (IP Source Guard) Jumbo Frames L2PT – Layer 2 Protocol Tunneling MAC Authentication Bypass MLD Snooping Multicast Etherchannel Load Balancing NAC – L2 IEEE 802.1x NAC – L2 IP NAC – L2 IP with Auth Fail Open Packet-Based Storm Control Per Port Per VLAN Policing Port Security Port Security on Private VLAN Ports Private VLANs QoS Policy Propagation via Border Gateway Protocol (QPPB) Rapid-Per-VLAN-Spanning Tree (Rapid-PVST) Reduced MAC Address Usage Remote SPAN (RSPAN) Smart Port Spanning Tree Protocol (STP) – Loop Guard Spanning Tree Protocol (STP) – PortFast BPDU Filtering Spanning Tree Protocol (STP) – Portfast Support for Trunks Spanning Tree Protocol (STP) – Root Guard Spanning Tree Protocol (STP) – Uplink Load Balancing SRR (Shaped Round Robin) Standby Supervisor Port Usage STP Syslog Messages Switching Database Manager (SDM) Trunk Failover Trusted boundary (extended trust for CDP devices) Unicast Mac Filtering UniDirectional Link Detection (UDLD) VLAN Access Control List (VACL) VLAN Aware Port Security Weighted Tail Drop (WTD)
