Branch Gateway services

VLAN configuration

In Branch Gateway, you can configure VLANs on fixed LAN ports.
G450 Branch Gateway supports up to 64 VLANs.
The following VLAN features are supported:
• VLAN port grouping. You can use port VLANs to group LAN ports into logical groups.
• Ingress VLAN Security. You can configure a list of ingress VLANs on each port. Any received
packets tagged with an unlisted VLAN are dropped.
• Class of Service (CoS) tagging. Packets are tagged with VLANs per CoS.
• Inter-VLAN routing. You can configure specific VLANs to permit access to WAN and others to
deny access to WAN.

Rapid Spanning Tree Protocol

The IEEE 802.1D (STP) and IEEE 802.1w Spanning Tree Protocols (RSTP) are supported on
ETH LAN ports.

Port mirroring

Branch Gateway support network traffic monitoring by port mirroring. You can configure port
mirroring on any LAN port. You can implement port mirroring by connecting an external traffic
probe device to one of the LAN ports. The probe device monitors traffic that is sent and received
through other ports by copying the packets and sending them to the monitoring port.

Port redundancy

You can configure port redundancy on Branch Gateway. Port redundancy enables you to provide
both a primary link and a backup link to a resource.

Link Layer Discovery Protocol

Link Layer Discovery Protocol (LLDP) simplifies network troubleshooting and enhances the ability
of network management tools to discover and maintain network topologies in multi-vendor
environments. LLDP defines a set of advertisement messages (TLVs), a protocol for transmitting
TLVs, and a method for storing the information in received TLVs. As a result, stations attached to a
LAN can advertise information about the system and station point of attachment to other stations
in the same LAN. This information can be reported to the management station through SNMP
MIBs.
