12 ExtremeWare 7.4.3 Installation and Release Notes
Overview
IP ARP Proxy Command Feature
The configure iparp add proxy command now configures the always qualifier independent of the
MAC address configuration. Configuring the IP ARP proxy entry without a mac_address and adding
always as a qualifier prompts the switch to send the ARP response with the mac_address of the switch.
The switch also answers all the ARP requests without filtering requests that belong to the same subnet
of the receiving router interface. You can configure up to 64 proxy ARP entries.
configure iparp add proxy <ip address> {<mask>} {<mac_address>} {always}
Local Authentication for Management Access When RADIUS Server
is Enabled
ExtremeWare 7.4 supports local authentication for management sessions if either RADIUS or TACACs
is enabled and the servers are configured. Currently, local authentication is performed:
• If both RADIUS/TACACs are disabled
• No RADIUS/TACACs servers are configured
• RADIUS/TACACs servers are not responding
With this new feature, you have the ability to perform local authentication for management sessions
while continuing to use RADIUS authentication for Network Login sessions.
Mirroring for Untagged Ports on Summit 200/300/400 Platforms
In the current implementation of ExtremeWare, all packets sent to a mirrored-to port contain a VLAN
tag. When looking at the packets, it was easy to see which VLAN the packet was sent on. In
ExtremeWare 7.4, packets sent to a mirrored-to port no longer contain a VLAN tag. The mirrored-to
port looks like a port in a VLAN. The port is now added as an untagged port if requested by the user.
When the mirrored-to port is configured as "untagged,” all packets received or sent by any of the
mirrored ports are sent to the mirrored-to port without the tag.
Link Layer Discovery Protocol
The Link Layer Discovery Protocol (LLDP) is a Layer 2 protocol (IEEE standard 802.1ab) that is used to
determine the capabilities of devices such as repeaters, bridges, access points, routers, and wireless
stations. The ExtremeWare 7.4 support for LLDP enables devices to advertise their capabilities and
media specific configuration information, and to learn the same information from the devices connected
to it. The information is represented in Type Length Value (TLV) format for each data item. The 802.1ab
specification provides detailed TLV information.
The information distributed using LLDP is stored by its recipients in a standard Management
Information Base (MIB), making it possible for the information to be accessed by a Network
Management System (NMS) using a management protocol such as the Simple Network Management
Protocol (SNMP).
EAPS Licensing Consolidation for Summit 200/300/400 Switches
This feature allows you to configure multiple EAPS domains in the EAPS edge switch, provided all the
domains have the same set of ring ports. This allows the EAPS edge to be configured to participate in
EAPS spatial reuse of a ring.
