Be sure not to cut yourself from switch management \ud83d\ude42<\/p>\n
You should have SNMP enabled and configured on switch (user with permission to read and write). We are using there two functions to decompose and compose HEX-STRING readed from switch. Also SNMP PHP package need to be compiled and enabled.<\/p>\n
Full example, we are removing port 10 from VLAN1 and adding port 9 tagged:<\/p>\n
