ETHERNET INTERFACE

IPmux-16L includes the following Ethernet ports:

• Three Gigabit Ethernet ports (SFP or UTP)
• Three Fast Ethernet ports (SFP or UTP).

All ports can be used for network or user connection. They support autonegotiation, VLAN tagging and rate limiting.

ETHERNET CAPABILITIES

IPmux-16L features an internal bridge, operating in VLAN-aware and VLAN-unaware modes, supporting up to 4k VLANs.
Each Ethernet port features:

• Rate limiting for bandwidth control
• Four priority queues (strict or weighted) for handling traffic with different service demands. Traffic is classified according to IP Precedence, 802.1p, DSCP or port default priority.
• VLAN membership for ingress traffic restriction
• VLAN tagging
• Double VLAN tagging (VLAN stacking)
• Bridging and filtering.

The device supports standard IP features, such as ICMP (ping), ARP, next hop and default gateway. Ingress and egress rate can be limited per user and network port. Rate limitation can be configured per packet type as well.

MANAGEMENT

IPmux-16L can be configured and monitored locally via an ASCII terminal, or remotely via Telnet or Web browser. Management traffic can run over a dedicated VLAN. Software can be downloaded via a local
terminal using XMODEM/YMODEM, or remotely, using TFTP. After downloading a new software version, IPmux-16L automatically saves the previous version in non-volatile memory for backup purposes.

Also, copies of the configuration file may be downloaded and uploaded to a remote workstation for backup and restore purposes.

QoS

IPmux-16L performs VLAN tagging and priority labeling according to 802.1p&Q. Pseudowire packets could be assigned a dedicated VLAN ID and 802.1p bit.
The ToS or Diffserv of the outgoing pseudowire packets are user-configurable. This allows assigning pseudowire packets a higher priority in IP networks.
EXP bits are used for QoS marking of the TDMoMPLS traffic in MPLS networks.
