Hi all: We have met a problem on Cat9300 switch recently. The Catalyst 9300 as a access switch,and connect PC or IP Phone+PC.I find a symptom that is so strange，the mac address status from PC is shown 'static' by 'sho mac address-table ' command , and i didn't configure static mac address binding. A mac address will appear on another port and show 'static ' status after i disconnect the PC few hours.So it will make it PC cannot access the switch port next time.I must clear authen session on abnomal ports if i want to access. This issue happen on multiple ports. sw software version is 16.9.2. Here is the abnormal status: 'bbbb.xxxx.xxxx ' and 'bbbb.xxxx.xxxx ' are other PC's MAC address. 'aaaa.xxxx.xxxx ' is the PC which connect G1/0/1,and there is not other device on G1/0/1,only the PC 'aaaa.xxxx.xxxx '. interface GigabitEthernet1/0/1 switchport mode access switchport voice vlan 10 device-tracking attach-policy DT_Policy authentication event fail action authorize vlan 20 authentication host-mode multi-auth authentication open authentication order dot1x mab authentication port-control auto mab dot1x pae authenticator spanning-tree portfast Have you encountered such a problem?

HI everyone，   I am occuring a issue of bgp redistribution. There is a static route on Cisco Router 7200 , commands just like as below: #ip route 12.1.1.0 255.255.255.0  10.1.1.1 tag 10 route-map cisco per 10  match tag 10 router bgp 12  redistribute static route-map cisco   the static route can be shown in "show ip bgp" . After i change the static route ( i add a same static route with tag 20,i think it's can cover the same static route that done before): ip route 12.1.1.0 255.255.255.0 10.1.1.1 tag 20  route-map cisco per 10   no match tag 10   match tag 20   router bgp 12  redistri static route-map cisco   after change the config,i tried to "clear ip bgp * soft ,but there is no that route shown by "show ip bgp " command.  So,i delete the static route,and add it again: #no ip route 12.1.1.0 255.255.255.0 10.1.1.1  #ip route 12.1.1.0 255.255.255.0 10.1.1.1 tag 20 Then, i tried to "clear ip bgp * soft”，the static route is shown by "show ip bgp "   i want to know what reason about this issue, it's a expected?   Thanks ...
