of your organization. You can implement the following types of filters to secure traffic on
the IA 1100/1200:
•
Layer-2 source filters (block bridge traffic based on source MAC address)
•
Layer-2 destination filters (block bridge traffic based on destination MAC address)
•
Layer-2 flow filters (block bridge traffic based on specific source-destination pairs)
•
Layer-3 source filters (block IP traffic based on source IP address)
•
Layer-3 destination filters (block IP traffic based on destination IP address)
•
Layer-3 flow filters (block IP traffic based on specific source-destination pairs)
•
Layer-4 application filters (block traffic based on UDP or TCP source and destination
ports for IP)
Quality of Service
Although the IA 1100/1200 supplies non-blocking high-speed throughput, you can
configure the IA 1100/1200 to apply Quality of Service (QoS) policies during peak periods
to guarantee service to specific hosts, applications, and flows (source-destination pairs).
This is especially useful in networks where the traffic level can exceed the network
medium's capacity.
The IA 1100/1200 QoS is based on four queues: control, high, medium, and low. Control
traffic has the highest priority, high the second highest, and so on. The default priority for
all traffic is low.
You can configure QoS policies for the following types of traffic:
•
Layer-2 prioritization (802.1p)
•
Layer-3 and Layer-4 application flows
Statistics
The IA 1100/1200 can provide extensive statistical data on demand. You can access the
following types of statistics:
•
Layer-2 RMON and MIB II Statistics – Port statistics for normal packets and for errors
(packets in, packets out, CRC errors, and so on)
•
Layer-3 RMON v2 Statistics – Statistics for ICMP, IP, IP-interface, IP routing, IP
multicast, VLAN
•
Layer-4 RMON v2 Statistics – Statistics for TCP and UDP
