MAC (Media Access Control) Count Limit
You can limit the number of MAC addresses that may be dynamically learned on a port. You may
enable/disable the MAC count limit on individual ports.
IGMP Count Limit
You can limit the number of IGMP groups a subscriber on a port can join. You may enable/disable
the IGMP count limit on individual ports.
Static Multicast
Use static multicast to allow incoming frames based on multicast MAC address(es) that you specify.
This feature can be used in conjunction with IGMP snooping to allow multicast MAC address(es)
that are not learned by IGMP snooping. You can use static multicast to pass routing protocols, such
as RIP and OSPF.
IGMP Snooping
With IGMP snooping, group multicast traffic is only forwarded to ports that are members of that
group. IGMP snooping generates no additional network traffic, allowing you to significantly reduce
multicast traffic passing through your IES.
IGMP Proxy
The IES can act as an IGMP proxy device to reduce multicast traffic. It issues IGMP host messages
to a multicast router or server on behalf of the connected multicast hosts.
Broadcast Storm Control
Broadcast storm control limits the number of broadcast packets the management switch card
receives per second on its ports.
Secured Client
Configure up to four rules to allow up to four ranges of remote host IP addresses to access your
management switch card.
Profile Server
The profile server feature allows you to manage profiles on multiple IESs.
System Error Logging
The system error log will record error logs locally to the management switch card memory.
Configurable Alarms
The system allows you to customize the priority levels of individual alarms and the alarm severity
threshold for recording alarms on an individual port(s).
