DHCP statistics not matching, conf-mode generates incorrect pool name with dash
Closed, ResolvedPublicBUG

Description

DHCP pool statistics seem to be replacing any "_" in the pool name with a "-" which throws off the reporting.

Configuration shows pool name as: v0302-RLS2_Guest:

litz-guest-dhcp1# sh service dhcp-server shared-network-name v0302-RLS2_Guest
 authoritative
 domain-name z.com
 domain-search z.com
 name-server x.x.x.x
 name-server y.y.y.y
 name-server 9.9.9.9
 name-server 1.1.1.1
 ping-check
 subnet 10.192.16.0/21 {
     default-router 10.192.16.1
     domain-name z.com
     domain-search z.com
     enable-failover
     lease 86400
     name-server x.x.x.x
     name-server y.y.y.y
     name-server 9.9.9.9
     name-server 1.1.1.1
     ping-check
     range 100 {
         start 10.192.16.21
         stop 10.192.23.254
     }
 }

The root cause it generates incorrect pool name (conf mode) with a dash instead of an underscore

vyos@vyos:~$ show conf com | match dhcp

set service dhcp-server shared-network-name NET_01 subnet 192.0.2.0/24 range R1 start '192.0.2.21'
