SwOS uses a simple algorithm to ensure TCP/IP communication - it just replies to the same IP and MAC address packet came from.NO subnet mask against the IP address such as 172.16.1.1 or 10.1.1.1 seems to default to a /24 address range.
RB260 has a simple CPU just to ensure configuration management of the Gigabit switch-chip. The higher latency does not affect its switching capabilities and an access to the web GUI.Using them as a trunk 802.11Q e.g PC-> [ SFP -> Port 5 ->] -> RB912UAG-2HPnD and using a managament vlan #1000 with IP's on each device on the managment vlan. Allows me to ping right throu the 260GSP to the end device with <1ms on vlan 1000. But if I ping the 260GSP's management IP on vlan #1000, produces a constant 15mS result.. That aint right..
