The actual fact was that I had to find a solution by other means.Īt the end it was quite easy. Probably, I was using the wrong keywords in my queries, or Google was feeling that I was a different kind of user (or a completely different one), or something else. Using Wireshark Coloring Rules to Enhance Wi-Fi Pr.The closest solution I found was to use an external application and capture its output.Use Cisco IOS Software Checker to Manage Vulnerabi.Limit SSIDs & Data Rates to Maintain Network Performance.This should help you make sense of all these BSSIDs you now support! Vlan BSSID Clients PSP Pri HT Encr Key0 Key1 Key2 Ke圓 SSIDs MFP To view Unified BSSID mappings from the access point, issue the following command: (Cisco Controller) >show ap wlan 802.11a OFFICEAP01 To view Unified BSSID mappings using the controller, issue the following command: Beacons are sent out for each SSID, and each can support varying capabilities. The newer Cisco Unified wireless network only allows one option, using multiple BSSIDs. To view Autonomous BSSID mappings for either scenario, issue the following command: Enable multiple-BSSID globally with the command: dot11 mbssid, or on individual radios with the command: mbssid. Additionally, since beacons are sent for every BSSID, SSID broadcasting could be configured independently for each. The second option was to enable multiple-BSSID, which then created a unique BSSID for every SSID created on the radio.
It also made supporting different capabilities between SSIDs more difficult, since there was reliance on the client to perform active scanning and be able to correctly interpret differences between the beacon information and probe response information, if different. The restriction with this method was that only one of the SSIDs could be used in guest-mode, which was Cisco's terminology for broadcasting the SSID. This meant that only one beacon was sent out and supported all SSIDs configured on the radio. By default Autonomous access points supported multiple SSIDs overlaid on top of a single BSSID. The older Cisco Autonomous access points gave administrators this capability, but with two slightly different configuration options. Manual verification of the BSSID can be quicker in some cases. It may take a while for a protocol analyzer to capture a probe response or association response that includes the SSID.
This can get tricky at times, especially when SSIDs are not broadcast and client traffic is minimal.
However, with the common practice by most wireless manufacturers to use a unique BSSID for every SSID, administrators often have to figure out which BSSID maps to each SSID when performing protocol analysis. This is not a new concept, and has been around for quite some time. This is very beneficial to support varying wireless requirements using the same physical infrastructure. Modern enterprise-grade wireless networks have the ability to provision multiple SSIDs on the same radios.
