Administering Data-Links in Exclusive-IP Non-Global Zones
The dladm command is used from the global zone to administer data-links.
How to Use dladm show-linkprop
The dladm command can be used with the show-linkprop subcommand to show
the assignment of data-links to running exclusive-IP zones.
You must be the global administrator in the global zone to administer data-links.
- Become superuser, or assume the Primary Administrator role.
To create the role and assign the role to a user, see
Using the Solaris Management Tools With RBAC (Task Map) in System Administration Guide: Basic Administration.
- Show the assignment of data-links on the system.
global# dladm show-linkprop
Example 27-1 Using
dladm With the
show-linkprop subcommand
In the first screen, zone 49bge, which is assigned bge0 has not been booted
global# dladm show-linkprop
LINK PROPERTY VALUE DEFAULT POSSIBLE
bge0 zone -- -- --
ath0 channel 6 -- --
ath0 powermode ? off off,fast,max
ath0 radio ? on on,off
ath0 speed 11 --
1,2,5.5,6,9,11,12,18,24,36,48,54
ath0 zone -- -- --
Zone 49bge is booted.
global# zoneadm -z 49bge boot
The command dladm show-linkprop is run again. Note that the bge0 link is now assigned to 49bge.
global# dladm show-linkprop
LINK PROPERTY VALUE DEFAULT POSSIBLE
bge0 zone 49bge -- --
ath0 channel 6 -- --
ath0 powermode ? off off,fast,max
ath0 radio ? on on,off
ath0 speed 11 --
1,2,5.5,6,9,11,12,18,24,36,48,54
ath0 zone -- -- --
How to Use dladm set-linkprop
The dladm command can be used with the set-linkprop subcommand to temporarily
assign data-links to running exclusive-IP zones. Persistent assignment must be made through the
zonecfg command.
You must be the global administrator in the global zone to administer data-links.
- Become superuser, or assume the Primary Administrator role.
To create the role and assign the role to a user, see
Using the Solaris Management Tools With RBAC (Task Map) in System Administration Guide: Basic Administration.
- Use dladm set-linkprop with the -t to add bge0 to a running zone
called excl.
global# dladm set-linkprop -t -p zone=excl bge0
LINK PROPERTY VALUE DEFAULT POSSIBLE
bge0 zone excl -- --
Tip - The -p option produces a display using a stable machine-parseable format.
How to Use dladm reset-linkprop
The dladm command can be used with the reset-linkprop subcommand to reset
the bge0 link value to unassigned.
- Become superuser, or assume the Primary Administrator role.
To create the role and assign the role to a user, see
Using the Solaris Management Tools With RBAC (Task Map) in System Administration Guide: Basic Administration.
- Use dladm reset-linkprop with the -t to undo the zone assignment of the
bge0 device.
global# dladm set-linkprop -t -p zone=excl bge0
LINK PROPERTY VALUE DEFAULT POSSIBLE
bge0 zone excl -- --
Tip - The -p option produces a display using a stable machine-parseable format.
Troubleshooting
If the running zone is using the device, the reassignment fails and an
error message is displayed. See Exclusive-IP Zone Is Using Device, so dladm reset-linkprop Fails.
