Only the following services currently support the designation of an MIO/UMIO card for demux
functions: GGSN, SGW, PGW, HA and SAE-GW.
Ex-GW, L2TP, MME, NEMO and SGSN are not supported.
After the ASR 5500 has booted with demux functions running on an MIO/UMIO, you cannot configure
non-supported services. A maximum of eight Demux Managers are supported. Any attempt to add
more than eight Demux Managers will be blocked.
more than eight Demux Managers will be blocked.
Service/products requiring a large number of VPN Managers, VRFs and/or Demux Managers must not

With demux functions running on an MIO, the ASR 5500 supports a maximum of 10 contexts, 15
interfaces per context, with a maximum of 64 interfaces and 250 VRFs per system.
Implementation of this feature assumes that CEPS (Call Events Per Second) and the number of subscribers
will remain constant, and only the data rate will increase. This ensures that the CPU demand will not increase
on the MIO/UMIO.
