求助，交换机能ping通但是不能telnet

交换机上启用了本征vlan 地址为192.168.156.1
ena sec跟line vty 都配置了，能ping通，但是telnet就会失败


                                                         在模拟器上面做的
命令如下。。。

enable secret 5 $1$mERr$9cTjUIEqNGurQiFU.ZeCi1

interface Vlan156
ip address 192.168.156.2 255.255.255.0
!
!
line con 0
password cisco
login
!
line vty 0 4
password cisco
login
line vty 5 15
login
!
!
end

我看了一下，是ping不同VLAN的网段，能不能帮我看一下是哪里出了问题
