CHAPTER 4 GENERIC ATTRIBUTE REGISTRATION PROTOCOL (GARP) This appendix provides the following information: • Describes the switch operation when its ports are configured to operate under the Generic Attribute Registration Protocol (GARP) applications – GARP VLAN Registration Protocol (GVRP) and/or GARP Multicast Registration Protocol (GMRP).
Chapter 4: Generic Attribute Registration Protocol (GARP) The purpose of GVRP is to dynamically create VLANs across a switched network. When a VLAN is declared, the information is transmitted out GVRP configured ports on the switch in a GARP formatted frame using the GVRP multicast MAC address (01-80-C2-00-00-21). A switch that receives this frame, examines the frame, and extracts the VLAN IDs. GVRP then creates the VLANs and adds the receiving port to its tagged member list for the extracted VLAN ID(s).
GARP Multicast Registration Protocol (GMRP) Configuring a VLAN on an 802.1Q switch creates a static GVRP entry. The entry will always remain registered and will not time out. However, dynamic entries will time-out and their registrations are removed from the member list if the end station A is removed. This ensures that if switches are disconnected, or if end stations are removed, the registered information remains accurate.
Chapter 4: Generic Attribute Registration Protocol (GARP) 4.3 GARP OPERATION STATUS SCREEN The GARP Operation Status screen, Figure 4-2, is used to enable ports on the switch as GMRP- and GVRP-aware ports. The ports may be enabled one by one or all at the same time for GMRP and GVRP. To access the GARP Operation Status screen, use the arrow keys to highlight the GARP OPERATION STATUS menu item on the 802.1 Configuration Menu screen and press ENTER. The GARP Operation Status screen displays.
GARP Operation Status Screen GVRP (Toggle) Sets the port to operate as a GVRP-aware port. The setting is only valid if the GVRP Protocol field near the bottom of the screen is set to Enable. The GMRP field setting toggles between Y (yes) and N (no). The default is “Y”. To set the port, refer to Section 4.3.1. Set All Ports (Selectable) Sets all ports to the same setting by selecting one of the following: • GMRP Enable All – Sets all ports as GMRP-aware ports. All ports are set to Y under GMRP.
Chapter 4: Generic Attribute Registration Protocol (GARP) GVRP Protocol (Toggle) Enables or disables the GVRP Protocol on the switch. When set to Enable, all port settings are valid for GVRP enabling those ports to send/receive frames to other GVRP-aware switches. Disable makes the port settings invalid. The default setting is “Disable”. To enable or disable the protocol, refer to Section 4.3.2. 4.3.1 Setting a Port to Operate in GMRP or GVRP To set a port to be a GMRP or GVRP aware port.
GMRP Configuration Screen 3. Press ENTER. 4. Use the arrow keys to highlight the SAVE command at the bottom of the screen. 5. Press ENTER. The message “SAVED OK” displays. 4.4 GMRP CONFIGURATION SCREEN The GMRP Configuration screen, Figure 4-3, is used to set the GMRP operation mode of each port. To access the GMRP Configuration screen, use the arrow keys to highlight the GMRP GROUP REGISTRATIONS menu item on the 802.1 Configuration Menu screen and press ENTER. The GMRP Configuration screen displays.
Chapter 4: Generic Attribute Registration Protocol (GARP) Mode (Selectable) Select one of the following four modes of operation: • Use GMRP Filter Unreg – Do not forward multicast addressed frames out this port that have an unregistered multicast address. • Forward All Groups – Regardless of multicast address registration, send all multicast addressed frames out this port.
GMRP Configuration Screen 4.4.2 Setting a Mode for All Ports The modes of operation are the same as the ones described in Section 4.4.1, except that all ports are affected. To set all the ports to operate in one mode, proceed as follows: 1. Use the arrow keys to highlight the Set All Ports field. 2. Press the SPACE bar to select one of the following modes of operation: • Use GMRP Filter Unreg • Forward All Groups • Filter All Groups • Use GMRP Forward Unreg 3. Press ENTER. 4.

Network Tools cdp Description: Allows management of Cabletron Discovery Protocol (CDP) on this device. This protocol is used by SmartSwitch device to discover other neighboring network devices and establish the topology of the network fabric. This protocol can also be used by the SmartSwitch device to propagate specific information to neighboring network devices.The user may enable, disable, or see the current status of CDP.
APPENDIX A ABOUT IGMP This appendix provides the following information: • IGMP Overview • Supported Features and Functions • Detecting Multicast Routers To configure the SmartSwitch device for IGMP operation, refer to Section 1.19 for instructions. A.1 IGMP OVERVIEW IGMP is a multicast protocol used by routers. This protocol is supported by Cabletron Systems SmartSwitches when operating in the 802.1Q mode to “snoop” the IGMP frames.
Appendix A: About IGMP • Supports stand alone multicast servers only if a router is present on the network. • Multicast forwarding rate is dependent on the number of ports to which the multicast stream is forwarded. More ports degrade the performance. • Supports IGMP version 1 and 2 only. Default is version 2. • Ports that are directly connected to routers are discovered dynamically through snooping for routing protocols. • IGMP is enabled or disabled per VLAN, and not per port.
Detecting Multicast Routers There are many multicast routing protocols that the switch supports. These include the following: • PIM version 1 and 2 • CBT (core based trees) • MOSPF • DVMRP The routing protocols are detected as follows: • All the multicast routing protocols have a destination address of 01-00-5E. • DVMRP and PIM version 1 run over IGMP. If the IGMP frame type is not a REPORT, QUERY, OR LEAVE, then the frame is assumed to be one of these.
