I'd argue that this describes VLAN interfaces.) not that the vendor is always right or anything, but at least one implementation (juniper) behaves this way: interfaces.ifTable.ifEntry.ifDescr.9 = fxp1.0 interfaces.ifTable.ifEntry.ifType.9 = ethernetCsmacd(6) interfaces.ifTable.ifEntry.ifSpeed.9 = Gauge: 100000000 interfaces.ifTable.ifEntry.ifDescr.36 = ge-2/0/0.401 interfaces.ifTable.ifEntry.ifType.36 = ethernetCsmacd(6) interfaces.ifTable.ifEntry.ifSpeed.36 = Gauge: 1000000000 crisco only creates entries in the ifTable for physical interfaces in their routers (or at least for the ones that I have access to that use .1q or isl). cisco msfc2 reports gigabit for vlans, but that doesn't count. just a reference point. I would argue that vlans are definitely "a sub-layer which has no concept of bandwidth" too. -- - bill fumerola / fumerola@yahoo-inc.com / billf@FreeBSD.org / billf@mu.org - my anger management counselor can beat up your self-affirmation therapist To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
