DHCP lease renewing ?

Fri Feb 10, 2023 3:29 pm

Dear Sirs,
we got 2 SXT SA5 in bridge both with DHCP Client enabled the first one got right the ip:
# INTERFACE  USE-PEER-DNS  ADD-DEFAULT-ROUTE  STATUS  ADDRESS        
0 ponte      yes           yes                bound   192.168.24.8/24
the second which is connected ad wireless client to the first instead show:
# INTERFACE  USE-PEER-DNS  ADD-DEFAULT-ROUTE  STATUS       ADDRESS         
0 ponte     yes           yes                renewing...  192.168.24.60/24
first:
Flags: X - disabled, R - running 
 0 R name="ponte" mtu=auto actual-mtu=1500 l2mtu=1600 arp=enabled 
     arp-timeout=auto mac-address=B8:69:F4:56:D5:05 protocol-mode=rstp 
     fast-forward=yes igmp-snooping=yes multicast-router=temporary-query 
     multicast-querier=no startup-query-count=2 last-member-query-count=2 
     last-member-interval=1s membership-interval=4m20s querier-interval=4m15s 
     query-interval=2m5s query-response-interval=10s 
     startup-query-interval=31s250ms igmp-version=2 mld-version=1 auto-mac=yes 
     ageing-time=5m priority=0x8000 max-message-age=20s forward-delay=15s 
     transmit-hold-count=6 vlan-filtering=no dhcp-snooping=no 
second:
Flags: X - disabled, R - running 
 0 R name="ponte" mtu=auto actual-mtu=1500 l2mtu=1600 arp=enabled 
     arp-timeout=auto mac-address=B8:69:F4:56:D5:00 protocol-mode=rstp 
     fast-forward=yes igmp-snooping=no auto-mac=yes ageing-time=5m 
     priority=0x8000 max-message-age=20s forward-delay=15s 
     transmit-hold-count=6 vlan-filtering=no dhcp-snooping=no

Can you please explain me why the second is with status renewing while expire after show more than 6 hours?
I've noticed that manually disabling and enabling the dhcp client take a lot of time on the second, instead in first is extremely fast.

RouterOS 7.7 on both

Thanks, BR
