An address-aging algorithm causes least-used addresses to fall out in favor of new
frequently used addresses. To reset the address buffer, cycle power down-and-up.
4.2 Auto-cross (MDIX), Auto-negotiation and Speed-sensing
The RJ-45 ports support auto cross (MDI or MDIX) in the auto-negotiation
mode according to the IEEE 802.3z standard. No crossover cables are needed when
connecting the CSG14’s to other unmanaged switches, legacy hubs, managed switches,
media-converters etc. Please note that there can be conditions with managed switches
where the switch manager fixes the port settings via software, and the result of the auto-
negotiation is changed in the managed switch by the manager commands. In such cases,
the 10/100/1000 speed or the F/H mode may be affected, but auto-cross in the CSG14
Switches will still work. The auto cross function cannot be disabled.
When an RJ-45 cable connection is made, and each time LINK is enabled,
auto-negotiation takes place (except for legacy products, which do not have auto-
negotiation and which go to the default state accordingly). The Magnum Switch
advertises its capability for 10, 100 or 1000Mbps speed and F/H duplex mode, and the
