(Paste verbatim output from pip freeze | grep napalm between quotes below)

napalm==3.2.0

(Paste verbatim output from show version - or equivalent - between quotes below)

IE4000  Software (IE4000-UNIVERSALK9-M), Version 15.2(4)EA9, RELEASE SOFTWARE (fc2)

Steps to Reproduce the Issue

1. Create a vlan with a space in the name on the switch.
2. Run device.get_vlans()

Looking at sh vlan br from the switch

Switch#sh vlan br

VLAN Name                             Status    Ports
---- -------------------------------- --------- -------------------------------
1    default                          active    Gi1/3, Gi1/4
10   PLC CONTROL NETWORK              active    Fa1/6, Fa1/7
14   OTHER IO NETWORK                  active    Gi1/2, Fa1/5, Fa1/8
1002 fddi-default                     act/unsup
1003 token-ring-default               act/unsup
1004 fddinet-default                  act/unsup
1005 trnet-default                    act/unsup

Looking at device.get_vlans()

{
    "1": {
        "name": "default",
        "interfaces": [
            "GigabitEthernet1/1",
            "GigabitEthernet1/3",
            "GigabitEthernet1/4"
        ]
    },
    "10": {
        "name": "PLC",
        "interfaces": []
    },
    "14": {
        "name": "OTHER",
        "interfaces": []
    },
    "1002": {
        "name": "fddi-default",
        "interfaces": [
            "GigabitEthernet1/1"
        ]
    },
    "1003": {
        "name": "token-ring-default",
        "interfaces": [
            "GigabitEthernet1/1"
        ]
    },
    "1004": {
        "name": "fddinet-default",
        "interfaces": [
            "GigabitEthernet1/1"
        ]
    },
    "1005": {
        "name": "trnet-default",
        "interfaces": [
            "GigabitEthernet1/1"
        ]
    }
}

I've traced it down to the regex on line ~3589 of _get_vlans_by_id in napalm/napalm/ios/ios.py, which doesn't support spaces in the vlan names.

interface_regex = r"{}\s+{}\s+\S+\s+([A-Z][a-z].*)$".format(
            vlan_id, vlan_name
        )

@alphabet5 Can you check the latest napalm version , if this works for you ? I have fixed it in #2010
