Switchport Ingress-Filtering; Switchport Mode - Supermicro SSE-G2252 User Manual

SSE-G2252/SSE-G2252P Switches User's Manual
Example
The following example shows how to add VLANs 1, 2, 5 and 6 to the allowed list as
tagged VLANs for port 1:
SSE-G2252(config)#interface ethernet 1/1
SSE-G2252(config-if)#switchport allowed vlan add 1,2,5,6 tagged
SSE-G2252(config-if)#

switchport ingress-filtering

This command enables ingress filtering for an interface. Use the no form to restore the
default.
Syntax
[no] switchport ingress-filtering
Default Setting
Disabled
Command Mode
Interface Configuration (Ethernet, Port Channel)
Command Usage
• Ingress filtering only affects tagged frames.
• If ingress filtering is disabled and a port receives frames tagged for VLANs for which
it is not a member, these frames will be flooded to all other ports (except for those
VLANs explicitly forbidden on this port).
• If ingress filtering is enabled and a port receives frames tagged for VLANs for which
it is not a member, these frames will be discarded.
• Ingress filtering does not affect VLAN independent BPDU frames, such as GVRP or
STA. However, they do affect VLAN dependent BPDU frames, such as GMRP.
Example
The following example shows how to set the interface to port 1 and then enable ingress
filtering:
SSE-G2252(config)#interface ethernet 1/1
SSE-G2252(config-if)#switchport ingress-filtering
SSE-G2252(config-if)#

switchport mode

This command configures the VLAN membership mode for a port. Use the no form to
restore the default.
