Interface Isolation

Interface isolation provides the ability to group interfaces in sets where traffic from each port is isolated from other interfaces in the group. The isolated interfaces in the group, however, are able to communicate with the interface marked as privileged.

  1. Create the VLANs to be used.

    Copy
    Copied!
                

    switch (config) # vlan 2-5 switch (config vlan 2-5) # exit

  2. Unlock isolation interface protocol.

    Copy
    Copied!
                

    switch (config) # protocol isolation-group

  3. Create isolation Group A.

    Copy
    Copied!
                

    switch (config) # isolation-group GroupA

  4. Assign VLANs 2 and 3 to isolation Group A.

    Copy
    Copied!
                

    switch (config isolation-group GroupA) # vlan 2-3 switch (config isolation-group GroupA) # exit

  5. Create isolation Group B.

    Copy
    Copied!
                

    switch (config) # isolation-group GroupB

  6. Assign VLANs 4 and 5 to isolation Group B.

    Copy
    Copied!
                

    switch (config isolation-group GroupB) # vlan 4-5 switch (config isolation-group GroupB) # exit

  7. Set Ethernet interfaces 1-3 to access for VLAN 3.

    Copy
    Copied!
                

    switch (config) # interface ethernet 1/1 switchport access vlan 3 switch (config) # interface ethernet 1/2 switchport access vlan 3 switch (config) # interface ethernet 1/3 switchport access vlan 3

  8. Isolate Ethernet interfaces 1 and 2 and set Ethernet interfaces 3 as privileged.

    Copy
    Copied!
                

    switch (config) # interface ethernet 1/1-1/2 isolation-group GroupA mode isolated switch (config) # interface ethernet 1/3 isolation-group GroupA mode privileged

  9. Enable isolation Group A.

    Copy
    Copied!
                

    (config) # isolation-group GroupA no shutdown

  10. Set Ethernet interfaces 4-6 to trunk.

    Copy
    Copied!
                

    switch (config) # interface ethernet 1/4 switchport mode trunk switch (config) # interface ethernet 1/5 switchport mode trunk switch (config) # interface ethernet 1/6 switchport mode trunk

  11. Isolate Ethernet interfaces 4 and 5 and set Ethernet interfaces 6 as privileged.

    Copy
    Copied!
                

    switch (config) # interface ethernet 1/4-1/5 isolation-group GroupA mode isolated switch (config) # interface ethernet 1/6 isolation-group GroupA mode privileged

  12. Enable isolation Group B.

    Copy
    Copied!
                

    switch (config) # isolation-group GroupB no shutdown

  13. Verify configuration.

    Copy
    Copied!
                

    switch (config) # show isolation-group Isolation group: GroupA State: Enabled VLANs: 2, 3 Privileged port: Eth1/3 Isolated ports: Eth1/1, Eth1/2   Isolation group: GroupB State: Enabled VLANs: 4, 5 Privileged port: Eth1/6 Isolated ports: Eth1/4, Eth1/5

protocol isolation-group

protocol isolation-group
no protocol isolation-group

Enables interface isolation and unlocks further isolation-group commands.
The no form of the command disables interface isolation and locks other isolation-group commands.

Syntax Description

N/A

Default

Disabled

Configuration Mode

config

History

3.6.1002

Example

switch (config) # protocol isolation-group

Related Commands

show isolation-group

Notes

  • MLAG must be disabled before enabling interface isolation

  • When disabled, all configuration is lost

isolation-group

isolation-group <name>
no isolation-group <name>

Creates isolation group.
The no form of the command deletes isolation group.

Syntax Description

N/A

Default

N/A

Configuration Mode

config

History

3.6.1002

Example

switch (config) # isolation-group mygroup
switch (config isolation-group mygroup) #

Related Commands

protocol isolation-group
show isolation-group

Notes

  • The no form of this command deletes the isolation group, removes its attached ports, and the VLANs from the group

  • Up to 64 isolation groups can be created

shutdown

shutdown
no shutdown

Disables isolation group.
The no form of the command enables isolation group.

Syntax Description

N/A

Default

Disabled

Configuration Mode

config isolation group

History

3.6.1002

Example

switch (config isolation-group mygroup) # no shutdown

Related Commands

protocol isolation-group
isolation-group
show isolation-group

Notes

Enabling isolation groups fails if there are VLANs with ports both inside and outside the group

vlan

vlan <vid>
no vlan <vid>

Adds a VLAN to isolation group.
The no form of the command removes a VLAN from an isolation group.

Syntax Description

N/A

Default

N/A

Configuration Mode

config isolation group

History

3.6.1002

Example

switch (config isolation-group mygroup) # vlan 10

Related Commands

protocol isolation-group
isolation-group
show isolation-group

Notes

  • Enabling isolation groups fails if there are VLANs with ports both inside and outside the group

  • The VLAN must be created before running this command

  • All interfaces in the VLAN must be attached to only this isolation group

  • The VLAN added cannot have a respective VLAN interface

isolation-group mode

isolation-group <name> mode {isolated | privileged}
no isolation-group <name> mode {isolated | privileged}

Adds a VLAN to isolation group.
The no form of the command removes a VLAN from an isolation group.

Syntax Description
