| May 22, 2013 at 20:37 | comment | added | generalnetworkerror | I primarily create L2 SVIs for statistical reporting (though limited as it is) and visibility on the switch as well as for a SNMP interface walk for Cacti (RRDTool graphs). The 74604 packets under L3 are just broadcasts shown by the next line "Received 74604 broadcasts". No other reason to create them except for comfort in having all interfaces defined whether L2 or L3. | |

Why do you create the L2 SVI in the first place (out of curiosity)? If this device doesn't have a L3 interface in this VLAN, where do the stats in your sh int vl281 command output above come from? Has this device in your question processed 74604 Ethernet frames across all layer 2 ports in the VLAN then? What can you tell from that output? I am assuming you create these L2 SVIs for statistic gathering and debugging/troubleshooting. Do you create them for use with pseudowires, briding and xconnects instead then?

Example of SVI L2 interface
|
| May 22, 2013 at 19:18 | comment | added | generalnetworkerror | I know most everyone considers that an SVI means we have a interface with an IP address. A L2 interface is still reported as an SVI by Cisco (EtherSVI). Am I wrong to use the term SVI for both L3 and L2 interfaces? | |

Clarified by removing SVI term.
