【网络 环境】地铁PIS系统正线
【设备型号】
AC:LSUM3WCMD0(V5)
轨旁AP:2620X(FIT)
车载AP:2620X(FAT)
【问题现象】
在AC的mesh接口下多放通一些vlan后导致全部列车车载AP空口利用率升高到50%到90+(业务流量和没增加之前一样),没增加vlan前列车车载AP空口利用率在10%-20%之间,网络正常;
【AC Mesh接口配置】
Mesh接口原配置:
interface WLAN-MESH1
port link-type trunk
port trunk permit vlan 1 20 1010 to 1011 1020 to 1021 1030 to 1031 1040 to 1041 1050 to 1051 1060 to 1061 1070 to 1071 1080 to 1081
port trunk permit vlan 1090 to 1091 1100 to 1101 1110 to 1111 1120 to 1121 1130 to 1131 1140 to 1141 1150 to 1151 1160 to 1161 1170 to 1171 1180 to 1181
port trunk permit vlan 1190 to 1191 1200 to 1201 1210 to 1211 1220 to 1221 1230 to 1231 1240 to 1241 1250 to 1251 1260 to 1261 1270 to 1271 1280 to 1281
port trunk permit vlan 1290 to 1291
port-security port-mode psk
port-security tx-key-type 11key
port-security preshared-key pass-phrase simple xxxxxx
Mesh接口增加vlan后配置:
interface WLAN-MESH1
port link-type trunk
port trunk permit vlan 1 20 1010 to 1011 1020 to 1021 1030 to 1031 1040 to 1041 1050 to 1051 1060 to 1061 1070 to 1071 1080 to 1081
port trunk permit vlan 1090 to 1091 1100 to 1101 1110 to 1111 1120 to 1121 1130 to 1131 1140 to 1141 1150 to 1151 1160 to 1161 1170 to 1171 1180 to 1181
port trunk permit vlan 1190 to 1191 1200 to 1201 1210 to 1211 1220 to 1221 1230 to 1231 1240 to 1241 1250 to 1251 1260 to 1261 1270 to 1271 1280 to 1281
port trunk permit vlan 1290 to 1291
port trunk permit vlan 1300 to 1521
port-security port-mode psk
port-security tx-key-type 11key
port-security preshared-key pass-phrase simple xxxxxx
