SNMPv3
IE switches support SNMPv1, SNMPv2c, and SNMPv3. Among other things, SNMPv3
provides user management at protocol level as well as security functions (for example
authentication). The configuration of users and groups for SNMPv3 is possible using Web
Based Management, the Command Line Interface or by direct access to the MIB objects
(only recommended for experts).
Syslog
Syslog according to RFC 3164 is used for transferring short, unencrypted text messages
over UDP in the IP network. This requires a standard Syslog server.
DHCP Option 82
The DHCP relay function allows the IP address initialization of an end device depending on
the connected switch port. DHCP Option 82 is supported with this function.
IGMP Snooping and IGMP Querier
IE switches support not only IGMP snooping but also the IGMP querier function. If IGMP
Snooping is enabled, IGMP packets are evaluated and the multicast filter table is updated
with this information. If IGMP Query is also enabled, IE switches also send IGMP queries
that trigger responses from IGMP-compliant nodes.
Only for SCALANCE X414-3E: Layer 3 functionality (routing)
You can also configure the SCALANCE X414-3E as a router. This allows various IP subnets
to be interconnected. You can enter static routes and/or enable RIP/OSPF and VRRP router
protocols. Using these standardized protocols, SCALANCE X414-3E can synchronize the
configuration with other routers in the network.
