# VLAN Mode/Tag Actions

VLAN-aware mode provides OPB administrators with the ability to match traffic based on the VLAN tag and redirect it to the tool port(s).

Push VLAN - Traffic replication to tool ports based on VLAN match and push new VLAN Tag

Pop VLAN - Traffic replication to tool ports based on VLAN match and pop VLAN Tag on egress traffic

The following image shows a visual representation of the VLAN Aware Mode and the VLAN Tag Actions:

### Configuration:

**Push VLAN:**

1. *Configure Network/Tool port(s)*

```
//Tool ports
configure terminal
interface ethernet Ethernet16/1
forward-error-correction rs
type tool
end
```

```
//Network ports
configure terminal
interface ethernet Ethernet12/1
forward-error-correction rs
type network
end
```

2\.  Configure VLAN aware-mode

```
configure terminal
interface ethernet Ethernet12/1
type network
mode vlan-aware
end
```

```
configure terminal
interface ethernet Ethernet16/1
egress-tagging enable
type tool
end
```

3\. Configure flow with Push VLAN

```
flow flow1
network-ports Ethernet12/1
tool-ports Ethernet16/1
push-vlan-tag 300
rule 1 permit match-all counters enable
end
```

4\. Verify

```
// verify interface
pbnoscli# show interface npb Ethernet12/1

pbnoscli# 
```

####

#### Pop VLAN:

1. *Configure Network/Tool port(s)*

```
//Tool ports
configure terminal
interface ethernet Ethernet16/1
forward-error-correction rs
type tool
end
```

```
//Network ports
configure terminal
interface ethernet Ethernet12/1
forward-error-correction rs
type network
end
```

2\.  Configure VLAN aware-mode

```
configure terminal
interface ethernet Ethernet12/1
type network
mode vlan-aware
end
```

```
configure terminal
interface ethernet Ethernet16/1
type tool
end
```

3\. Configure flow with Pop VLAN

```
flow flow1
network-ports Ethernet12/1
tool-ports Ethernet16/1
pop-vlan enable
rule 1 permit match-all counters enable
end
```

4\. Verify

```
