The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

This chapter describes the Cisco NX-OS virtual port channel (vPC) commands that begin with D.
To delay the virtual port channel (vPC) from coming up on the restored vPC peer device after a reload when the peer adjacency is already established, use the delay restore command. To revert to the default delay value, use the no form of this command.
delay restore {time | interface-vlan time}
no delay restore [interface-vlan]
time |
Number of seconds to delay bringing up the restored vPC peer device. The range is from 1 to 3600. |
interface-vlan |
Specifies the delay in bringing up the interface VLAN. |
30 seconds
vPC domain configuration mode
|
|
---|---|
5.0(3)N1(1) |
This command was introduced. |
5.1(3)N1(1) |
The interface-vlan keyword was added. |
Use the delay restore command to avoid upstream traffic from the access device to the core from being dropped when you restore the vPC peer devices.
This command does not require a license.
This example shows how to configure the delay reload time for a vPC link:
switch(config)# vpc domain 1
switch(config-vpc-domain)# delay restore 10
switch(config-vpc-domain)#
This example shows how to configure the delay reload time for an interface VLAN:
switch(config)# vpc domain 1
switch(config-vpc-domain)# delay restore interface-vlan 100
switch(config-vpc-domain)#

show vpc |
Displays the vPC configuration information. |
To enter a summary of the purpose of a port profile, use the description command. To remove the summary description for the port profile, use the no form of this command.
description text
no description
text |
Summary of the purpose of the port profile. The summary text can be a maximum of 80 characters and can include spaces. |
None
Port profile configuration mode
|
|
---|---|
5.2(1)N1(1) |
This command was introduced. |
This example shows how to enter a description for a port profile named ppEth to identify the purpose of the port profile:
switch# configure terminal
switch(config)# port-profile ppEth
switch(config-port-prof)# description Port profile to configure batch commands for Ethernet interfaces
switch(config-port-prof)#
To ensure that certain VLAN interfaces are not shut down on the virtual port-channel (vPC) secondary peer device when the vPC peer link fails for those VLANs carried on the vPC peer link but not on the vPC configuration itself, use the dual-active exclude interface-vlan command. To return to the default value, use the no form of this command.
dual-active exclude interface-vlan {range}
no dual-active exclude interface-vlan {range}
range |
Range of VLAN interfaces that you want to exclude from shutting down. The range is from 1 to 4094. |
None
vPC domain configuration mode
|
|
---|---|
5.0(3)N1(1) |
This command was introduced. |
The VLAN interfaces must have already been configured.
This command does not require a license.
This example shows how to configure the device to keep the VLAN interfaces up on the vPC peer devices if the peer link fails:
switch# configure terminal
switch(config)# vpc domain 5
switch(config-vpc-domain)# dual-active exclude interface-vlan 10
switch(config-vpc-domain)#

---|---|
copy running-config startup-config |
Copies the running configuration to the startup configuration. |
show vpc |
Displays vPC configuration information. |
