2911 -EOL I do not believe you get officially, but you may try with refurbished if you keen to buy.

you can add Ethernet switch modules :

Hello,

for the 2911, you can add a service module, an EHWIC, or an ISM (see the link below, scroll down to Table 3):

Assuming you can, do keep in mind Cisco recommends the 2911 for up to 35 Mbps, duplex.  (NB: the 2911 can often do more than 35 Mbps, but capacity varies greatly based on traffic mix and router features being used.)
