My Cisco Switch has below configuration:
spanning-tree mode pvst
no spanning-tree optimize bpdu transmission
spanning-tree extend system-id
no spanning-tree vlan 1
!
vlan internal allocation policy ascending
!
interface FastEthernet0
no ip address
--More-- shutdown

interface GigabitEthernet1/0/1
switchport access vlan 101
no cdp enable

interface GigabitEthernet1/0/7

switchport access vlan 103

snmp-server host 10.42.24.29 cisco snmp
10.42.239.33 is Firewall interface
10.42.24.29 is a workstation connected to Firewall
Each VLAN is connected to a Load balancer which default gateway is set to Firewall interface (10.42.239.33)
The question is :
1. The workstation cannot get SNMP data from the switch. WHY?
2. VLAN 102 has an NTP Server But I cannot get NTP Update from Switch. WHY?
Confirmed that Firewall policy is permitted traffic
ANYONE knows what happened?
Thanks.
