I have created systemd service to create a bond, and confirmed it's created successfully from the output in the logs, but I can not see the bond in my current shell.
mlx_bonding.service
[Unit]
Description=Create bonding with mlx_bond_0
[Service]
Type=simple
ExecStart=/root/scripts/bonding/mlx_bonding_start.sh
ExecStop=/root/scripts/bonding/mlx_bonding_stop.sh
[Install]

mlx_bonding_start.sh
#!/bin/bash
ip link add bond0 type bond

ip link set p1 up
ip link set bond0 up
ip link show dev bond0
cat /proc/net/bonding/bond0
The output:

You can see the bond is created in the log, and everything looks fine, but if I run commands to check the bond in shell
[root@dpu-bf2-105 bonding]# ls /proc/net/bonding/
[root@dpu-bf2-105 bonding]# ip link show type bond
[root@dpu-bf2-105 bonding]#
I can't see it.
What could be the possible reasons for that? Thank you so much
