14 Release Note
Software Release 2.6.4
C613-10404-00 REV A
Disable 10/100 Ports at the Hardware
Level
When disabling a port or group of ports on the switch, you can now specify
that 10/100 Ethernet ports are disabled at the hardware level, using the
command:
disable switch port={port-list|all} [link={enable|disable}]
[other-parameters...]
The link parameter specifies whether 10/100 Ethernet ports are either enabled
or disabled at the hardware level. If disable is specified, this is the equivalent
of disconnecting the cable. If the link parameter is not specified, the link
remains physically enabled. The default is enable.
If a port has been disabled at the hardware level, when it is reset it is enabled at
the hardware level and autonegotiation of speed and duplex mode is activated.
For more information, see the Switching chapter of the Software Reference.
Specifying the Mode of Operation When
IGMP Snooping is Enabled
You can now specify the mode of operation when IGMP Snooping is enabled
with the command:
set igmpsnooping routermode=[all|default|ip|multicastrouter|
none]
If all is specified, all reserved multicast addresses (i.e. 224.0.0.1 to 224.0.0.255)
are treated as router multicast addresses.
If default is specified, the following addresses are treated as router multicast
addresses:
• IGMP Query, 224.0.0.1
• All routers on this subnet, 224.0.0.2
• DVMRP Routers, 224.0.0.4
• OSPFIGP all routers, 224.0.0.5
• OSPFIGP designated routers, 224.0.0.6
• RIP2 routers, 224.0.0.9
• All PIM routers, 224.0.0.13
• All CBT routers, 224.0.0.15
If ip is specified, you specify addresses treated as router multicast addresses
using the add igmpsnooping routeraddress and the delete igmpsnooping
routeraddress commands. When in this mode, your switch retains previous
addresses that have already been specified.
If multicastrouter is specified, the following addresses are treated as router
multicast addresses:
• DVMRP Routers, 224.0.0.4
• All PIM routers, 224.0.0.13
