PCR: 03793 | Module: RSVP | Level: 3 |
The ENABLE RSVP INTERFACE command did not succeed if IP was enabled after the RSVP interface had been created. Now, ENABLE RSVP INTERFACE will succeed regardless of when IP is enabled as long as an IP interface exists.
PCR: 03799 Module: DHCP | Level: 3 |
When a new static entry was allocated to a client, an old dynamic entry remained inuse for a full lease period. This issue has been resolved. The old entry will now be reclaimed when the client attempts to renew its lease and receives the new static entry.
IGMP Snooping All-Group Entry
Because IGMP is an
IGMP snooping enables the switch to forward multicast traffic intelligently on the switch. The switch listens to IGMP membership reports, queries and leaves messages to identify the switch ports that are members of multicast groups. Multicast traffic will only be forwarded to ports identified as members of the specific multicast group.
This enhancement allows network managers to prevent specified ports from acting as IGMP
For example, consider a video streaming service which has 15 channels. When the switch receives IGMP membership reports destined for the address
239.0.0.2from an unauthorised user, all 15 channels of multicast data floods to that port, which may affect the service of the network. In order to avoid this, the network manager decides whether or not to allow a particular port to behave as an IGMP
Commands
This enhancement modifies one command:
■SHOW IP IGMP
and has two new commands:
■ENABLE IP IGMP ALLGROUP
■DISABLE IP IGMP ALLGROUP
