Restrictions for cGVRP
•A device other than a Cisco device can only interoperate with a Cisco device through .1Q trunks.
•VLAN mapping is not supported with GVRP.
•cGVRP and Connectivity Fault Management (CFM) can coexist but if the line card (LC) or supervisor does not have enough mac-match registers to support both protocols, the cGVRP ports on those LCs are put in error disabled state. To use Layer 2 functionality, disable cGVRP on those ports and configure shut/no shut.
•cGVRP functionality applies only to interfaces configured for Layer 2 (switchport) functionality.
•Native VLAN tagging causes frames sent to the native VLAN of the .1Q trunk ports to be encapsulated with .1Q tags. Problems may arise with other GVRP participants on the LAN if they cannot admit tagged GVRP Protocol Data Unit (PDU)s. Caution must be exercised if both features are enabled at the same time.
•802.1X authentication and authorization takes place after the port becomes link-up and before the Dynamic Trunking Protocol (DTP) negotiations start prior to GVRP running on the port.
•Port security works independently from GVRP and it may be limited to the number of other GVRP participants on a LAN with which a GVRP enabled port on a device can communicate.
•GVRPs cannot be configured and run on a subinterface.
•GVRP and UniDirectional Link Routing (UDLR) should not be enabled on the same interface because UDLR limits frames in one direction on the port and GVRP is a two way communication protocol.
•Additional memory is required to store GARP/GVRP configurations and states per GVRP enabled port, but it can be dynamically allocated on demand.
•GARP Multicast Registration Protocol (GMRP) is not supported.
Information About cGVRP
To configure cGVRP, you should understand the following concepts:
•GVRP Interoperability with VTP and VTP Pruning
•GVRP interoperability with Other Software Features and Protocols
GARP/GVRP Definition
GVRP enables automatic configuration of switches in a VLAN network allowing network devices to dynamically exchange VLAN configuration information with other devices. GVRP is based on GARP which defines procedures for registering and deregistering attributes with each other, eliminating unnecessary network traffic by preventing attempts to transmit information to unregistered users.
GVRP is defined in IEEE 802.1Q.
cGVRP Overview
GVRP is a protocol that requires extensive CPU time in order to transmit all 4094 VLAN states on a port. In Compact mode only one PDU is sent and it includes the states of all the 4094 VLANs on a port.
VLAN pruning can be accomplished more quickly by running in a special mode, Fast Compact Mode, and on point-to-point links.
In Compact GVRP a GVRP PDU may be sent from the port if the port is in a forwarding state of a spanning tree instance. GVRP PDUs must be transmitted in the native VLAN of .1Q trunks.
GVRP Interoperability with VTP and VTP Pruning
VLAN Trunk Protocol (VTP) Pruning is an extension of VTP. It has its own Join message that can be exchanged with VTP PDUs. VTP PDUs can be transmitted on both .1Q trunks and Inter-Switch Link (ISL) trunks. A VTP capable device is in either one of the three VTP modes: Server, Client, or Transparent.
When VTP Pruning and GVRP are both enabled globally, VTP Pruning is run on ISL trunks, and GVRP is run on .1Q trunks.
Compact GVRP has two modes: Slow Compact Mode, and Fast Compact Mode. A port can be in Fast Compact Mode if it has one GVRP enabled peer on the same LAN segment and if the peer is capable of operating in Compact Mode. A port is in Slow Compact Mode if there are multiple GVRP participants on the same LAN segment operating in Compact Mode.
GVRP interoperability with Other Software Features and Protocols
STP
Spanning Tree Protocol (STP) may run in one of the three STP modes: Multiple Spanning Tree (MST), Per VLAN Spanning Tree (PVST), or Rapid PVST. An STP mode range causes the forwarding ports to leave the forwarding state as STP has to reconverge. The need to reconverge may cause GVRP to have its own topology change because Join messages may be received on some new ports and Leave timers may expire on some others.
DTP
Dynamic Trunking Protocol (DTP) negotiates the port mode (trunk vs. nontrunk and the trunk encapsulation type between two DTP enabled ports. After negotiation DTP may set the port to either ISL trunk, or .1Q trunk, or nontrunk. DTP negotiation occurs after ports become link-up and before they become forwarding in spanning trees. If GVRP is administratively enabled on a port and the device, it should be initialized after the port is negotiated to be a .1Q trunk.
VTP
VTP version 3 expands the range of VLANs that can be created and removed via VTP. VTP Pruning is available for VLAN states 1 to 1005 only.
EtherChannel
When multiple .1Q trunk ports are grouped by either Port Aggregation Protocol (PAgP) or Link Aggregation Control Protocol (LACP) to become an EtherChannel, the EtherChannel can be configured as a GVRP participant. The physical ports in the EtherChannel cannot be GVRP participants by themselves. Since an EtherChannel is treated like one virtual port by STP, the GVRP application can learn the STP state change of the EtherChannel just like any physical port. The EtherChannel, not the physical ports in the channel, constitutes the GARP Information Propagation (GIP) context.
High Availability
High Availability (HA) is a redundancy feature in Cisco IOS software. On platforms that support HA and State SwitchOver (SSO), many features and protocols may resume working in a couple of seconds after the system encounters a failure such as a crash of the active supervisor in a Catalyst 7600 switch. GVRP needs to be configured to enable user configurations, and protocol states should be synched to a standby system. If there is a failure of the active system, the GVRP in the standby system, which now becomes active, has all the up-to-date VLAN registration information.
