Traffic Prioritization – This switch prioritizes each packet based on the required level of
service, using four priority queues with strict priority or Weighted Round Robin Queuing.
They use IEEE 802.1p and 802.1Q tags to prioritize incoming traffic based on input from
the end-station application. These functions can
be used to provide independent priorities
for delay-sensitive data and best-effort data.
This switch also supports several common methods of prioritizing layer 3/4 traffic to meet
application requirements. Traffic can be prioritized based on the DSCP field in the IP
frame. When these services are enabled, the priorities are mapped to a Class of Service
value by this switch, and the traffic then sent to the corresponding output queue.
Quality of Service – Differentiated Services (DiffServ) provides policy-based
management mechanisms used for prioritizing network resources to meet the
requirements of specific traffic types on a per-hop basis. Each packet is classified upon
entry into the network based on access lists, IP Precedence or DSCP values, or VLAN
lists. Using access lists allows you select traffic based on Layer 2, Layer 3, or Layer 4
information contained in each packet. Based on network policies, different kinds of traffic
can be marked for different kinds of forwarding.
Multicast Filtering – Specific multicast traffic can be assigned to its own VLAN to ensure
that it does not interfere with normal network traffic and to guarantee real-time delivery by
setting the required priority level for the designated VLAN. This switch uses IGMP
Snooping and Query to manage multicast group registration. They also support Multicast
VLAN Registration (MVR) which allows common multicast traffic, such as television
channels, to be transmitted across a single network-wide multicast VLAN shared by hosts
residing in other standard or private VLAN groups, while preserving security and data
isolation for normal traffic.
Tunneling – Configures tunnels for customer traffic crossing the service provider’s
network using IEEE 802.1Q.
IEEE 802.1Q Tunneling (QinQ) – This feature is designed for service providers carrying
traffic for multiple customers across their networks. QinQ tunneling is used to maintain
customer-specific VLANs and Layer 2 protocol configurations even when different
customers use the same internal VLAN IDs. This is accomplished by inserting Service
Provider VLAN (SPVLAN) tags into the customer’s frames when they enter the service
provider’s network, and then stripping the tags when the frames leave the network.
Link Layer Discovery Protocol – LLDP is used to discover basic information about
neighboring devices within the local broadcast domain. LLDP is a Layer 2 protocol that
advertises information about the sending device and collects information gathered from
neighboring network nodes it discovers.
