Can we use the T320 instead of the M320 at network edge ?

I needed to know the answers on the below bold questions that were asked by a Network manager , i tried to answer them , but i want to get some confirmation that the T320 can work in the edge , exept for the couple of not supported PIC card all should work like the M320 right ? The RE has the L3 tables and does the routing and the JUNOS lets say 11.1 contains the commands , is there something that missed ?
Any advise help is very appreciated ! :mrgreen:
Q:What are the limitations for: policers, virtual interfaces, filters for this device?-Commands are Junos software release specific and since most of the same RE and same Junos can be used on both T320 and M320 routers I think there is almost no difference in configuration commands on both series ….perhaps when a type of PIC card is not supported in the T-series the commands will also not work. (for PIC/FPC support see bottom of the email)
-Both platforms support policers .
-What virtual interfaces are you referring too?
-On the data-sheet you can see that large filter lists are supported , hundreds of thousands of filter lists. (See attachment with filter based forwarding info.)
Q:Is the T320-FPC3, “Internet Processor 2” based? since any features depend on this. Juniper’s Internet Processor 1 is very outdated:-The T320 FPC’s use a T-series internet processor , the corresponding T-series FPC’s have the same forwarding rates as the M320 series FPC’s(see links)
Also the M320/T320/T640 SIB forwarding rates in Mpps are similar.
SIB Packet Forwarding Characteristics
Routing per Second (Mpps) Number of
Platform Forwarding SIBs per Chassis Redundancy
M320 385 4 No
T320 320 3 Yes
T640 640 5 Yes
T-series internet processor information :
The T Series architecture allows all Junos OS features and services
to operate across many interface types without compromising
performance. All platforms are highly secure with large filter lists
(hundreds of thousands of firewall filter terms) and rate limiting
to mitigate denial of service (DoS) attacks. Consistent hardware based
QoS features such as deep packet classification, filtering,
and granular queuing are deployable at large scale for many
Backed by the industry’s widest breadth of software services,
T Series Routers are designed on a foundation of IP/MPLS optimized
hardware that offers unique packet handling
functionality unmatched for its flexibility and scale. The result is
robust quality of service (QoS) for rich and scalable voice transport,
video distribution, multicast replication, traffic engineering, ATM-to-
MPLS migration, and IP transit and peering services.
Most M-series PIC’s also work in the T-series except the ones below, so when you need some of these interfaces you are forced to use the M-series (see attachment for supported PIC’s ) :
PIC’s not supported in the T320/T640
Link Services PIC, 4 ML bundles
Link Services PIC, 32 ML bundles
Link Services PIC, 128 ML bundles
ChT1, IQ, 10-port
ChE1, IQ, 10-port
1-Gigabit Ethernet IQ2, 8-port SFP oversubscription
OC-3c/STM-1, 2-port ( m7i/m10i only)
OC-3/STM-1, 2-port SFP ( m7i/m10i only)
E3 IQ, 2-port ( m7i/m10i only)
Almost all PIC are supported due to 3 different types of T320-FPC’s :
T320-FPC1 T320 Flexible PIC Concentrator (accepts M160 FPC1 PICs)
T320-FPC2 T320 Flexible PIC Concentrator (accepts M160 FPC2 PICs)
T320-FPC3 T320 Flexible PIC Concentrator (accepts PC series PICs)
The M320 series router is a real multifunctional edge router .
