The
fourth byte
from the right is always replaced by 01:00:5e during conversion. See
example below:
The group is added to the list of existing static multicast groups. This list, which is displayed
in a list box, is referred to as "dot1qStaticMulticastTable" in SNMP.
Port assignment
After entering a new group in the "Multicast Group Address" field, add the ports of the group
members by selecting the corresponding checkboxes. Confirm by entering your password
and clicking on "Apply".
Because of the conversion from IP to MAC addresses, you should avoid using IP
addresses that differ with regard to the third byte from the right by 128. Example:
Both multicast IP addresses are converted into the multicast MAC address
01:00:5e:1e:75:d8.
3rd byte
from the right
1st multicast IP address:
2nd multicast IP address:
Difference:
Settings are not automatically saved permanently. The active configuration can be saved
permanently by selecting "Save current configuration" on the "Configuration
Management" web page.
