Hi bjmango,
As port #443 is known protocol for HTTPs over TCP, we can block TCP protocol port=443 as below:
[Step1: create IP ACL rule, deny TCP destination port=443]
ip access-list test
deny tcp any any eq 443
permit ip any any
exit[Step2: binding IP ACL to interface 1/0/6]
interface 1/0/6
ip access-group test in 1
exitBesides: If you want only permit packet with port=443, deny other packet. We need change IP ACL rule as below:
permit tcp any any eq 443
deny ip any anyFor detailed configuration of IP ACL function, please refer to CLI User Manual for Manged Switch, refer to the link (page 940: IP Access Control List Commands).
