华为eNSP三层架构网络配置，pc1端ping只能ping自己，别的pc端ping不出来

各部分配置代码
sw3
system-view
sysname sw3
vlan 10
int e0/0/1
port link-type access
port default vlan 10
dis this
return
system-view
int gi0/0/1
port link-type trunk
port trunk allow-pass vlan 10
dis this
return
save

sw4
system-view
sysname sw4
vlan 20
int e0/0/1
port link-type access
port default vlan 20
dis this
return
system-view
int e0/0/2
port link-type trunk
port trunk allow-pass vlan 20
dis this
return
save

汇聚层sw2
system-view
sysname sw2
vlan batch 10 20
port-group group-member gi0/0/1 to gi0/0/2 e0/0/1
port link-type trunk
port trunk allow-pass vlan 10 20
return
save

核心层core
system-view
sysname core
vlan batch 10 20
int gi0/0/1
port link-type trunk
port trunk allow-pass vlan 10 20
dis this
dis port vlan
int vlanif 10
ip address 192.168.10.1 24
qu
int vlanif 20
ip address 192.168.20.1 24
dis ip int brief
return
save

你再细心检查一下汇聚交换机的trunk配置。原则上来说你汇聚与接入交换机之间的trunk需要配置一致的允许vlan。你PC1 ping其他不通，PC2呢？
