Switch SM-ES3G-16-P issue

george.mikoyan891 · ‎07-05-2015

Hi dear engineers.

I have a cisco3945e router with SPE slot SM-ES3G-16-P swith module connected.

SM-ES3G-16-P switch has 18 gigabit ethernet ports (2 uplink and 16 external).

Two uplink gigabit ethernet ports of the Switch are connected to the Router inside of the Router case.
External 16 ports are also gigabit ethernet ports.

It mean that if rate of each external port is more than 125 Mb/sec then total rate of all 16 ports is more than 2Gb/sec and Switch can't forward traffic rapidly, which become a cause of some issues.

Question: Can I in some way to increase a bandwidth of two internal ports
by software, IOS commands or making some change in hardware, like
replace gigabit to 10 gigabit????????

I cannot use twinging connectors to make faster (10Gb), beacause Switch SM-ES3G-16-P is a slot of my c3945e router

Please see jpeg file below

Thanks in advance

Actually, a 3945E is recommend (by Cisco) for up to 350 Mbps of WAN (i.e. duplex) bandwidth, so it's questionable whether it could even well support the dual gig of internal bandwidth to the switch module.
