Frequently Asked Questions
|
|
==========================
|
|
|
|
**Outer VLAN header not captured in PCAP?**
|
|
|
|
Some interface drivers drop the outer VLAN header. The BNG Blaster tries to
|
|
recover the VLAN from kernel headers but will not change the packets stored
|
|
in the PCAP file.
|
|
|
|
**Some sessions established on BNG are not established on BNG Blaster?**
|
|
|
|
The BNG Blaster considers a session only as established if all configured
|
|
protocols are established. This could occur if the device under test (your BNG)
|
|
is configured for IPv4 only but the BNG Blaster is configured for IPv4 and IPv6.
|
|
|
|
The idea here is to prevent potential failures will be overseen.
|
|
|
|
**DHCPv6 does not start for PPPoE sessions?**
|
|
|
|
The BNG Blaster expects an ICMPv6 router-advertisement with an other-config flag
|
|
before it starts sending DHCPv6 within a PPPoE session.
|
|
|
|
**Why is stream length limited to 3936 bytes?**
|
|
|
|
The stream length limit is dynamically calculated depending on the configured
|
|
IO mode. The default mode using Packet MMAP limits the stream length to pagesize
|
|
minus internal header and overhead (ethernet, MPLS, ...) which results in 3936 bytes
|
|
on most systems. The IO mode RAW would allow streams with up to 9000 bytes. |
