LANCOM GS-2124
Quality of Service
DiffServ/TOS
Port based (VIP Port), 802.1p, Priority queuing of packets based on DiffServ/TOS fields
Port priority
Supports four level priority queues to prioritize inbound and outbound traffic
Supports priority in a Q-in-Q
Q-in-Q Tagging
QoS Control List
Provides four internal queues to support four different classifications of traffic; packets can be classified as VIP ports, 802.1p,
DiffServ and/or IP TOS, IPv4 and UDP/TCP applications. The QoS operates at full wire speed and each egress port can be
scheduled according to strict, weighted round robin or mixed.
Security
MAC address limitation
802.1x
MAC address learning limit, to set up the maximum amount of MAC that each port can learn
802.1x access control on all ports, user- or MAC-based
Access control lists
Broadcast Storm Control
Isolated Group
Filtering of IP or MAC addresses and protocols - integrated setup assistant
Multicast/Broadcast/Unknown unicast storm suppression
Allows certain ports to be designated as protected. All other ports are non-isolated. Traffic between isolated group members ist
blocked. Traffic can only be sent from isolated group to non-isolalted group.
