It is recommended that these protocols be turned off on the Catalyst 2950 interfaces that connect to the Catalyst 2948G-元 switch. The Catalyst 2948G-元 switch does not support negotiation protocols found on other Catalyst switches, such as VLAN Trunk Protocol (VTP), Dynamic Trunking Protocol (DTP), and Port Aggression Protocol (PAgP). If you want two or more interfaces to belong to the same subnet, bridging needs to be configured on these interfaces. Since all of the interfaces are routed interfaces, each interface has to belong to a different network or subnet. The Catalyst 2948G-元 switch does not extend your VLANs by default.
It uses a Cisco IOS command line and by default, all interfaces are routed interfaces. Background Theoryįrom a configuration standpoint, the Catalyst 2948G-元 switch is a router. If you are working in a live network, ensure that you understand the potential impact of any command before using it. All of the devices used in this document started with a cleared (default) configuration. The information presented in this document was created from devices in a specific lab environment.
SETTING UP CISCO 2950 SWITCH SOFTWARE
The information in this document is based on the software and hardware versions below.Ĭatalyst 2948G-元 switch running Cisco IOS® Software 12.0(14)W5(20)Ĭatalyst 2950 switch running Cisco IOS Software 12.1(12c)EA1 For details and specific caveats or guidelines on individual switches, refer to the following documents:Ĭatalyst 2950 Switch Configuring EtherChannelĬatalyst 2950 Switch ConfiguringVLAN TrunksĬatalyst 2948G-元 Switch Configuring EtherChannelĬatalyst 2948G-元 Switch Configuring VLAN Encapsulation This document describes the sample configuration from the switches and the output from the related show commands. Before You Begin Conventionsįor more information on document conventions, see the Cisco Technical Tips Conventions. FEC, GEC, port channel, and channel group refers to EtherChannel in this document. In this configuration example, two Fast Ethernet interfaces on a Catalyst 2950 switch are bundled into a FEC with two Fast Ethernet interfaces from a Catalyst 2948G-元 switch. Catalyst 2948G-元 and Catalyst 4908G-元 switches share the same software image, so the Catalyst 2948G-元 configuration used in this document also applies to the Catalyst 4908G-元 switch. Note: The Catalyst 2950 switch supports only 802.1Q trunking, and does not support Inter-Switch Link Protocol (ISL) trunking. EtherChannel can be called Fast EtherChannel (FEC) or Gigabit EtherChannel (GEC) depending upon the speed of the interfaces or ports used to form the EtherChannel. This document describes the set-up of an EtherChannel and 802.1Q trunking between Catalyst 2950 and Catalyst 2948G-元 switches.
