If I can have a config snippit it would be great.
Since a few people asked about this, I figured it would be OK to post to
the list.
The configuration of an 802.1q trunk on a cFPC interface really isn't much
different from configuring an 802.1q trunk on similarly capable
interfaces. You can configure different sub-interfaces with different
MTUs. The physical interface (and whatever is at the other end) should
be using an MTU that's as large as, or larger than whatever you're using
on the sub-ifs.
interfaces {
xe-0/0/0 {
description "10G trunk for XYZ aggregation";
vlan-tagging;
mtu 9192;
unit 100 {
description "Customer A";
vlan-id 100;
family inet {
mtu 9000;
filter {
input CUST-A-INGRESS;
output CUST-A-EGRESS;
}
address xxxxxxxx/27;
}
family inet6 {
mtu 9000;
filter {
input CUST-A-V6INGRESS;
output CUST-A-V6EGRESS;
}
address xxxxxxxx/64;
}
}
unit 101 {
description "Customer B";
vlan-id 101;
family inet {
mtu 1500;
filter {
input CUST-B-INGRESS;
output CUST-B-EGRESS;
}
address xxxxxxxx/29;
}
}
}
}
This is on a 10G cFPC in an M120:
FPC 0 REV 05 710-015908 xxxxxx M120 CFPC 10GE
PIC 0 BUILTIN BUILTIN 1x 10GE(LAN/WAN) XFP
Xcvr 0 REV 01 740-014279 xxxxxxxxxxxx XFP-10G-LR

Yes. I use some 10G cFPCs in pretty much this manner on a pair of M120s at
work. They've been running that way for the past 4 years with no major
issues. I can send a config snippit if needed.
Also can double tagging be configured on it as well. Please let me if any
one has based any restriction on the cFPC 10G interfaces.
I don't know about double-tagging/QinQ support, as I don't use those
features.
