Release Notes for Cisco Aironet 1410 Bridges for Cisco IOS Release 12.2(15)JA
OL-5264-01
Caveats
Telnet Session Sometimes Hangs or Will Not Start During Heavy Traffic
When the bridge is transmitting and receiving heavy traffic, you sometimes cannot start a Telnet session
and some existing Telnet sessions freeze or hang. However, this behavior is expected because the bridge
gives top priority to data traffic and a lower priority to Telnet traffic.
