smaller than the TDMoIP header, saving about 5% in bandwidth (depending on
the actual frame size).
Bundling
A bundle is a logical internal Vmux-210 port, containing up to 30 timeslots.
Vmux-210 supports 12 bundles. A bundle is routed to a defined remote IP
address. Each timeslot can be included in any bundle. At the remote site, it can
be connected to any timeslot within a destination bundle.
Bundle QoS supports:
• Labeling IP level priority (ToS).
• VLAN tagging and priority labeling according to IEEE 802.1D&Q.
The user can configure the ToS (Type of Service) of the outgoing IP packets. This
allows an en-route layer 3 router or switch that supports ToS to give higher
priority to Vmux-210 traffic for delay-sensitive and secure applications.
Vmux-210 allows you to configure the whole ToS byte field, since different
vendors may use different bits to tag packets for traffic prioritization. This also
enables you to work according to various RFC definitions (for example RFC 2474,
RFC 791).
Internal Switch and VLAN Tagging for Security and QoS
All traffic between:
• Ethernet ports
• Ethernet port and voice port
• Ethernet port and E1/T1/Serial Uplink
• Ethernet port and the host
is routed through the Vmux-210’s built-in Ethernet switch. This switch enables
optional VLAN tagging of the various traffic, as well as blocking unrecognized
traffic.
VLAN Table
Vmux-210 includes a VLAN table, which can contain up to 64 entries. Each entry
defines the egress and tagging policies for packets with a specific VLAN ID, for
each port. Packets with a particular VLAN ID can be blocked.
Internal Router
Vmux-210 includes an internal router, which supports the following features:
• DHCP server, client, or relay
• NAT
• Firewall
• Static and dynamic routing
• RIP1 and RIP2.
