Netgear XCM8810 - 8800 SERIES 10-SLOT CHASSIS SWITCH ユーザーズマニュアル

NETGEAR 8800 Chassis Switch CLI Manual for information on the defaults for individual 
commands.

The term VR is also used with the Virtual Router Redundancy 

Protocol (VRRP). VRRP uses the term to refer to a single VR that 
spans more than one physical router, which allows multiple switches 
to provide redundant routing services to users. 

Types of Virtual Routers

The following sections introduce the two types of VRs in an XCM8800 system:

The system VRs are the three VRs created at boot-up time. These system VRs cannot be 
deleted or renamed. They are named VR-Mgmt, VR-Control, and VR-Default. The following 
describes each system VR:

VR-Mgmt enables remote management stations to access the switch through Telnet, 
SSH, and SNMP sessions; and it owns the management port. No other ports can be 
added to VR-Mgmt, and the management port cannot be removed from it.

The Mgmt VLAN is created in VR-Mgmt during XCM8800 system boot-up. No other 
VLAN can be created in this VR, and the Mgmt VLAN cannot be deleted from it.

No routing protocol is running on or can be added to VR-Mgmt.

VR-Control is used for internal communications between all the modules and subsystems 
in the switch. It has no external visible ports, and you cannot assign any port to it.

VR-Control has no VLAN interface, and no VLAN can be created for it.

No routing protocol is running on or can be added to VR-Control.

VR-Default is the default VR created by the XCM8800 system. By default, all data ports in 
the switch are assigned to VR-Default. Any data port can be added to and deleted from 
VR-Default.

Users can create and delete VLANs in VR-Default. The Default VLAN is created in 
VR-Default during the XCM8800 system boot-up. The Default VLAN cannot be deleted 
from VR-Default.
