4.6.5.60 <RSTP [IFACE] MA [6..40]
This parameter sets Maximum Age parameter. According to the IEEE 802.1D:2004 standard the
Maximum Age parameter declares the node number in the chain, that will discard the BPDU
packet that root-bridge sends. Every node in the chain will compare “Age” value in BPDU and will
drop the packet if its “Age” will be greater than Maximum Age.

4.6.5.61 <RSTP [IFACE] PRIO [0..240]> Command
This command selects interface priority. The value should be multiple by 16. The port priority
intended to resolve situation when several interfaces have the same root path cost. The port with
lowest port priority will be selected then. Available interfaces are:
• LAN1 – LAN5
• WAN 1, 2, 3, 4
• MWAN 1, 2
