DELL OS10 Vlans ACL or Portchannel ACL
Hi All.
I have a dell switch S4148T. In the configuration are defined multiple vlans.
The switch has trunk port for all vlans to connect vmware esxi node.
Routing mode is enabled.
Example vlan and routing
SW# show ip route
Codes: C - connected
S - static
B - BGP, IN - internal BGP, EX - external BGP, EV - EVPN BGP
O - OSPF, IA - OSPF inter area, N1 - OSPF NSSA external type 1,
N2 - OSPF NSSA external type 2, E1 - OSPF external type 1,
E2 - OSPF external type 2, * - candidate default,
+ - summary route, > - non-active route
Gateway of last resort is via 10.1.0.253 to network 0.0.0.0
Destination Gateway Dist/Metric Last Change
----------------------------------------------------------------------------------------------------------
*S 0.0.0.0/0 via 10.1.0.253 vlan1 1/0 24 weeks 5 days 05:12:16
C 10.1.0.0/16 via 10.1.0.245 vlan1 0/0 24 weeks 5 days 05:11:45
C 10.100.20.0/23 via 10.100.21.250 vlan20 0/0 24 weeks 5 days 05:11:43
C 10.100.110.0/24 via 10.100.110.214 vlan110 0/0 24 weeks 5 days 05:11:43
C 10.100.30.0/24 via 10.100.30.214 vlan30 0/0 24 weeks 5 days 05:11:43
C 10.100.50.0/24 via 10.100.50.244 vlan50 0/0 24 weeks 5 days 05:11:43
The physical link to the esxi node is made with a portchannel (two interfaces eth1, eth2) in trunk on all vlans. The tagged is applied by vmware vSwitch.
In this situation it's possible to apply ACLs to limit some address ports to each vlan ? Multipel ACLs for different vlans ?
It' better to make a single acl to apply to the single portchannel or ethernet ?
Example:
allow tcp/53, upd/53 to host 10.100.20.233, 10.100.20.234 from all vlan
deny tcp/3389 to any host from all vlan except vlan 110.
...
I undestand that applying ACLs to a VLAN, that is effectively the same thing as applying the ACL to all ports that belong to that VLAN.
Thanks for support.

Hello, I think yes it's possible to apply ACLs to limit some address ports to each VLAN. You can also have multiple ACLs for different VLANs. An example how you might configure ACLs
Hope that helps!
