Fd.io pages states following in the “create sub-interfaces” section: Example of how to created a subinterface to process untagged packets: vpp# create sub-interfaces GigabitEthernet2/0/0 5 untagged
I am trying to do exactly same thing mentioned above and it fails. Is this a known issue (a bug) ?? -vijay From: "Chandra Mohan, Vijay Mohan" <vijch...@ciena.com> Date: Tuesday, September 18, 2018 at 2:37 PM To: "vpp-dev@lists.fd.io" <vpp-dev@lists.fd.io> Subject: Failing to create untagged sub-interface Was not sure if this email is being delivered properly or not, so, sending a new email with the old email trail: Looking to understand the significance of “SUBINT_CONFIG_VALID” flag. When is it set and why ? untagged sub-interface creation fails when this flag is set. Question is when is this flag being set at first place ?? Does this flag indicate that a valid vlan is configured on this interface ? Still looking in to the code but, so far, did not find any instance in the configuration code path (up until “ethernet_sw_interface_add_del”) where this flag is being set. -vijay From: "Chandra Mohan, Vijay Mohan" <vijch...@ciena.com<mailto:vijch...@ciena.com>> Date: Wednesday, September 12, 2018 at 10:16 AM To: "vpp-dev@lists.fd.io<mailto:vpp-dev@lists.fd.io>" <vpp-dev@lists.fd.io<mailto:vpp-dev@lists.fd.io>> Subject: Re: Unable to create sub-interface with 'untagged' option Just wanted to check if you anyone got a chance to look at this ? Am I missing some configuration here before creating a sub-interface for untagged frames ? -Vijay From: "Chandra Mohan, Vijay Mohan" <vijch...@ciena.com<mailto:vijch...@ciena.com>> Date: Thursday, September 6, 2018 at 3:57 PM To: "vpp-dev@lists.fd.io<mailto:vpp-dev@lists.fd.io>" <vpp-dev@lists.fd.io<mailto:vpp-dev@lists.fd.io>> Subject: Re: Unable to create sub-interface with 'untagged' option Did anyone get a chance to take a look at this ? -vijay From: "Chandra Mohan, Vijay Mohan" <vijch...@ciena.com<mailto:vijch...@ciena.com>> Date: Wednesday, September 5, 2018 at 1:35 PM To: "vpp-dev@lists.fd.io<mailto:vpp-dev@lists.fd.io>" <vpp-dev@lists.fd.io<mailto:vpp-dev@lists.fd.io>> Subject: Unable to create sub-interface with 'untagged' option Hi All, Creation of a sub-interface with ‘untagged’ option fails with the message “ create sub-interfaces: vlan is already in use” . Any idea what I am missing here ? There is no other configs present and trying to create sub-interface for the first time. vpp# create sub-interfaces GigabitEthernet5/0/0 1 untagged create sub-interfaces: vlan is already in use Thanks, Vijay
