JUNOS 10.1 Network Interfaces Configuration Guide
NOTE: Channelized intelligent queuing (IQ) and channelized enhanced intelligent
queuing (IQE) interfaces require M Series Enhanced Flexible PIC Concentrators (FPCs)
and MX Series Enhanced Flexible PIC Concentrators (FPCs).
Wherever JUNOS configuration guides refer to channelized interfaces and PICs without
the "intelligent queuing IQ or IQE" descriptor, they are referring to the original
channelized interfaces and PICs.
On M40e routers, all supported interface types support a maximum number of 784
traffic-bearing interfaces that can be created per interface port and includes ports
on channelized PICs.
MX Series routers support two Type 2 Channelized IQ PICs: OC12/STM4 IQE PIC
with SFP and OC48/STM16 IQE PIC with SFP. Each channelized OC12/STM4 PIC
supports 4 ports, and the channelized OC48/STM16 PIC supports one port.
T640 and TX Matrix routers support Type 3 Channelized IQE PICs: 4xCOC12 IQE
PIC with SFP.
Channelized 4xCOC12 IQE PICs support deep-channelization of up to six OC slices
(STS1) per port. For example, only six OC slices can be channelized to CT1/T1 or
CE1/E1.
Channelized COC48 IQE PICs support deep-channelization of up to six OC slices
(STS1) in a block of 12 contiguous OC slices. For example, only six OC slices out of
OC slice 1-12 can be channelized to CT1/T1 or CE1/E1. The PIC supports
deep-channelization of maximum 24 OC slices in this way.
Channelized OC48 IQE PICs do not support STS-48 clear-channel mode.
IQ and IQE PICs do not support aggregated SONET (link bonding).
For channelized IQ and IQE logical interfaces, you can configure class of service
(CoS). For more information, see the JUNOS Class of Service Configuration Guide.
Channelized Interface Capabilities
You can configure each port of a channelized IQ PIC or channelized IQE PIC as a
single interface that uses the entire available bandwidth, or partition each port into
smaller data channels. In either case, you start with a channelized interface
(designated by a
interfaces, you configure data channels. Following are the channelized interface
names and data-channel interface names associated with channelized IQ and IQE
PICs.
