Does a STA need to be reauthenticated or re-logged in during STA roaming? Do the STA's subnet properties (including the IP address, home VLAN, ACL, and priority) change

24

During STA roaming, the STA does not need to be reauthenticated or re-logged in. In addition, the STA's subnet properties are inherited, so they do not change.

During STA roaming, STA subnet attributes such as the IP address, VLAN, ACL, and priority are inherited and will not be changed.

When a STA is roaming, whether reauthentication or re-login is required
No reauthentication or re-login is required when a STA is roaming.

What STA information can be displayed on a WLAN device
1. Number of STAs associated with an AP For V200R005, run the display station assoc-num command. For V200R006, run the display station ap-id xx command. 2. STA information For V200R005, run the display station assoc-info sta sta-mac command. For V200R006, run the display station sta-mac sta-mac command. The display contents vary depending on versions. The following uses V200R005C10 as an example: display station assoc-info sta d420-6df4-f37e Station mac-address : d420-6df4-f37e //STA mac Station ip-address : 0.0.0.0 //STA IP Station gateway : 0.0.0.0 Associated SSID : jsldoc //SSID Station online time(ddd:hh:mm:ss) : 000:00:04:20 //Online time The upstream SNR(dB) : 30.0 The upstream aggregate receive power(dBm) : -79.0 Station connect rate(Mbps) : 23 //Rate Station connect channel : 1 //Channel Station inactivity time(ddd:hh:mm:ss) : 000:00:00:00 ...... Station's RSSI(dBm) : -66 //Single strength Station's Noise(dBm) : -109 Station's radio mode : 11b //Network type Station's AP ID : 6 //AP ID (supported only by V200R005C00) Station's Radio ID : 0 //0 indicates 2.4G, and 1 indicates 5G (supported only by V200R005C00). Station's Authentication Method : OPEN Station's Cipher Type : NO CIPHER Station's User Name : d4206df4f37e Station's Vlan ID : 28 Station's Channel Band-width : 20MHz Station's asso BSSID : dcd2-fc9a-2110 Station's state : Asso with auth Station's Qos Mode : NULL Station's HT Mode : - Station's MCS value : 0 Station's NSS value : 0 Station's Short GI : support Station's roam state : No

Does an online 802.11b/g STA affect the rate of another online 802.11n STA
Yes. 802.11b/g STAs have a low rate and occupy the air interface for a longer time when forwarding the same traffic as 802.11n STAs. This lowers the rate of an online 802.11n STA.

Viewing IP addresses of STAs that are obtained dynamically
On an AC or a Fat AP, run the following command to view STA IP addresses that are dynamically obtained: - If the IP addresses are assigned from an interface address pool, run the display ip pool interface interface-pool-name used command. If the IP addresses are assigned from a global address pool, run the display ip pool name ip-pool-name used command. - To view access information about all STAs, run the display station all command. You can know the IP address assigned to each STA based on the mapping between IP addresses and MAC addresses.
