12.07DC...

NRP1#sh int f0/0/0
FastEthernet0/0/0 is up, line protocol is up
  Hardware is AmdFE, address is 0050.736f.9109 (bia 0050.736f.9109)
  MTU 1500 bytes, BW 100000 Kbit, DLY 100 usec,
     reliability 255/255, txload 5/255, rxload 30/255
  Encapsulation ARPA, loopback not set
  Keepalive set (10 sec)
  Full-duplex, 100Mb/s, 100BaseTX/FX      

NRP1 uptime is 3 days, 5 hours, 1 minute
