Parameters

evi-link [ interface-number ]: Specifies EVI-Link interfaces. If you specify an EVI-Link interface, this command displays information about the specified interface. If you specify only the evi-link keyword, this command displays information about all EVI-Link interfaces. If you do not specify the evi-link [ interface-number ] option, this command displays information about all interfaces.

brief: Displays brief interface information. If you do not specify this keyword, the command displays detailed interface information.

description: Displays the complete interface description. If you do not specify this keyword, the command displays only the first 27 characters of the interface description string.

down: Displays interfaces that are physically down as well as the down reason. If you do not specify this keyword, the command does not filter output by physical interface state.

Usage guidelines

The command output includes the PVID, link type, tunnel source address, tunnel destination address, and EVI network ID.

Examples

# Display detailed information about EVI-Link 0.

<Sysname> display interface evi-link 0
EVI-Link0
Current state: UP
Description: EVI-Link0 Interface
PVID: 1
Port link-type: trunk
 VLAN Passing:   none
 VLAN permitted: none
 Trunk port encapsulation:  IEEE 802.1q
This EVI-link belongs to Tunnel0
Source 1.1.1.1, Destination 1.1.2.1
Network ID 1

Table 17: Command output

Field	Description
Current state	EVI-Link interface state: DOWN—Physical state of the interface is down. UP—Physical state of the interface is up.
Description	Interface description.
PVID	Port VLAN ID of the interface.
Port link-type: trunk	Interface link type, fixed at trunk.
VLAN Passing	VLANs that have been created and allowed to pass through the interface. For EVI-Link interfaces, this field always displays none.
VLAN permitted	VLANs to which the interface has been assigned. They do not necessarily have been created. For EVI interfaces, this field always displays none.
Trunk port encapsulation	Link layer protocol of the interface.
This EVI-link belongs to Tunnel0	EVI tunnel that conveys the EVI link.
Source	Local tunnel address of the EVI link.
Destination	Remote tunnel address of the EVI link.
Network ID	EVI network ID of the EVI link. This network ID is configurable on the EVI tunnel interface.

# Display brief information about EVI-Link 0.

<Sysname> display interface evi-link 0 brief
Brief information on interface(s) under bridge mode:
Link: ADM - administratively down; Stby - standby
Speed or Duplex: (a)/A - auto; H - half; F - full
Type: A - access; T - trunk; H - hybrid
Interface            Link Speed   Duplex Type PVID Description
ELNK0                UP   --      --     T    1

# Display physically down EVI-Link interfaces and the down reason.

<Sysname> display interface evi-link brief down
Brief information on interface(s) under bridge mode:
Link: ADM - administratively down; Stby - standby
Interface            Link Cause
ELNK0                DOWN Not connected

Table 18: Command output

Field	Description
Brief information on interface(s) under bridge mode	Brief information about the physical Layer 2 interface for the EVI-Link interface.
Interface	Interface name abbreviation.
Link	Physical state of the interface: UP—Physical state of the interface is up. DOWN—Physical state of the interface is down. ADM—The interface has been administratively shut down. To bring it up, use the undo shutdown command. Stby—The interface is in standby state.
Speed	Interface rate in bps.
Duplex	Duplex mode of the interface: A—Autonegotiation mode. The duplex mode depends on the result of the negotiation with the remote end. F—Full duplex. F(a)—The result of the autonegotiation is full duplex. H—Half duplex. H(a)—The result of the autonegotiation is half duplex.
Type	Link type: A—Access. T—Trunk. H—Hybrid.
PVID	Port VLAN ID of the interface.
Description	Interface description set with the description command. If you execute the display interface brief command without the description keyword, this field displays up to 27 characters. If you execute the display interface brief command with the description keyword, this field displays the complete interface description.
Cause	Down reasons: Administratively—The physical link has been shut down with the shutdown command. To bring it up, use the undo shutdown command. Not connected—No physical link is present, for example, because no cable is connected to the port or because the cable is damaged.
