Chapter 1 Getting to Know Your MSC
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-5000.
IGMP Proxy
The IES-5000 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).
Multiple Management Logins
The management switch card can support multiple concurrent management sessions.
Remote Firmware Upgrade
You can use FTP or SFTP to perform configuration backup/restore and firmware upgrade from
a remote location.
